Description

  The present invention relates to a saddle-ride type vehicle equipped with a fuel cell that generates electric power by reacting fuel supplied from a fuel container.

Conventionally, some saddle-riding vehicles such as motorcycles travel using the electric power generated by the fuel cell. Such saddle-riding vehicles contain fuel to be supplied to the fuel cell. A fuel container is installed. In such a saddle-ride type vehicle, it is required that as much fuel as possible can be mounted in order to extend the cruising distance. However, when the fuel container is enlarged, it becomes difficult to install the fuel container on the vehicle body. For this reason, the storage pressure in the fuel container is increased so that more fuel can be accommodated, or a plurality of fuel containers are mounted on a saddle-ride type vehicle (for example, Patent Documents). 1). In this saddle-ride type vehicle (fuel cell two-wheeled vehicle), two fuel containers (fuel cylinders) are installed at intervals on the left and right sides of the rear part of the vehicle body. A rear seat is provided above both fuel containers.
JP 2007-99008 A

  However, in the conventional saddle riding type vehicle described above, by providing two fuel containers, the width of the rear side portion of the saddle riding type vehicle is increased and the rear part of the saddle riding type vehicle is heavy, so that the weight of the vehicle body is increased. The balance gets worse. Further, since the vehicle width is increased by arranging the two fuel containers side by side, when the occupant is seated on the rear seat, it is necessary to widen the crotch and straddle the seat. For this reason, it becomes difficult for the occupant to get on the rear seat of the saddle-ride type vehicle, and it is necessary to maintain a state where the crotch is greatly expanded after sitting, so that the occupant cannot sit in an easy posture.

  The present invention has been made in order to address the above-described problems. The object of the present invention is to provide two fuel containers that are easy to get on the seat, can be seated on the seat in a more comfortable posture, and have a good weight balance between the front and rear. It is to provide a saddle-ride type vehicle equipped with.

  In order to achieve the above-described object, the constitutional feature of the saddle-ride type vehicle according to the present invention is a saddle-ride type vehicle that travels with electric power generated by a fuel cell by reacting fuel supplied from a fuel container. The fuel container is composed of a pair of sealed cylindrical containers that are long in the axial direction, and the pair of fuel containers are approximately at the center in the width direction of the body of the saddle-ride type vehicle with the axial direction facing the front-rear direction. It is that they are mounted in a line in the front-rear direction.

  In the saddle-ride type vehicle according to the present invention, the pair of fuel containers elongated in the axial direction substantially matches the axial direction with the central axis extending in the front-rear direction of the vehicle body when the saddle-ride type vehicle is viewed from above. In this way, they are mounted in a line in the front-rear direction. That is, the pair of fuel containers are arranged so as to extend in a straight line when viewed from above with the longitudinal direction directed in the front-rear direction of the vehicle body. For this reason, it is possible to prevent the vehicle width of the part equipped with the fuel container from becoming large, and it is not necessary for the passenger to get on board or to sit in a state where the crotch is widened widely, and boarding and sitting in an easy posture Will be able to. In addition, the weight balance between the front and rear of the saddle-ride type vehicle can be made good. The saddle riding type vehicle according to the present invention includes vehicles such as motorcycles, motor tricycles, motor vehicles, and snow vehicles.

  Further, another structural feature of the saddle-ride type vehicle according to the present invention is that a supply pipe portion for supplying fuel toward the fuel cell is provided on one end side of the pair of fuel containers, respectively. A pair of fuel containers are arranged such that one end sides of the fuel tanks face each other and the supply pipe portions of the pair of fuel containers approach each other. According to this, when the fuel respectively supplied from the pair of supply pipe portions is connected to a predetermined connection pipe and the fuel is supplied to the fuel cell through the connection pipe, the predetermined connection pipe is shortened. Therefore, the connection structure for connecting the pair of supply pipes and the fuel cell can be made compact.

  Still another structural feature of the saddle-ride type vehicle according to the present invention is that the positions in the height direction of both supply pipe portions are shifted in the vertical direction. According to this, since the supply pipes of the pair of fuel containers can be brought close to each other without interfering with each other and overlapped vertically, the front and rear of the saddle-ride type vehicle occupied by the fuel container can be increased accordingly. The installation space in the direction is not lengthened. In other words, when the fuel containers are mounted on the saddle-ride type vehicle, the fuel containers can be prevented from interfering with each other even though the fuel containers are arranged so as to approach each other. In addition, since the positions in the height direction of the two supply pipes of the pair of fuel containers are shifted in the vertical direction, a space for operating the supply pipes and performing maintenance work can be secured.

  Still another structural feature of the saddle-ride type vehicle according to the present invention is that a main frame that inclines downward from the front side to the rear side of the vehicle body while supporting the front suspension device, and The vehicle body frame is composed of a seat frame that is connected to the rear portion and supports the seat and tilts upward from the front side to the rear side of the vehicle body, and one of the pair of fuel containers is located above the main frame. Is disposed along the inclination of the main frame, the other of the pair of fuel containers is disposed along the inclination of the seat frame on the upper side of the seat frame, and the seat is disposed above the portion where the pair of fuel containers face each other. It is to be arranged.

  According to this, since the seat is arranged above the mutually opposed portions of the pair of fuel containers respectively arranged along the inclination of the main frame having a lowered rear side and the seat frame having a lowered front side, It is not necessary to increase the height of the seat. This improves the ease of getting on and off the saddle-ride type vehicle. Also, since one fuel container is supported by the main frame and the other fuel container is supported by the seat frame, the weight of the pair of fuel containers can be dispersed and supported by the main frame and the seat frame. Concentrate the weight of the fuel container on the frame and avoid loading. Furthermore, since the pair of fuel containers can be arranged close to the center of gravity located at the approximate center in the front-rear direction of the saddle-ride type vehicle, the weight balance of the vehicle body is further improved.

  Still another structural feature of the saddle-ride type vehicle according to the present invention is that a supply pipe portion for supplying fuel toward the fuel cell is provided on one end side of the pair of fuel containers, respectively. A pair of fuel containers are arranged so that one end sides of the containers are opposed to each other and the supply pipe portions of the pair of fuel containers are close to each other, and the seat frame is configured by a member having a rod-like portion parallel to the left and right. The supply pipe portions of the pair of fuel containers are arranged between the rod-shaped portions of the seat frame. According to this, each supply pipe part of a pair of fuel containers can be protected by the seat frame. In this case, the main frame is composed of a pair of frames, and each frame is connected to both front end portions of the rod-shaped portion of the seat frame.

  In addition, another constitutional feature of the saddle-ride type vehicle according to the present invention is that one fuel container is fixed to the main frame and the other fuel container is fixed to the seat frame, and the main frame is subjected to external force. When the rear part of the seat frame is deformed relatively upward, the fuel container fixed to the main frame is located outside the range of the trajectory when the fuel container fixed to the seat frame moves with the deformation of the seat frame. There is in doing so.

  In this case, it is preferable to make the strength of the seat frame smaller than the strength of the main frame. According to this, the strong main frame is inclined so that the rear side is lower than the front side, and the seat frame having a lower strength than the main frame is inclined so that the rear side is higher than the front side. For example, when a saddle-ride type vehicle is bumped from behind by another vehicle and the seat frame is deformed, the rear portion of the seat frame is likely to be deformed relatively upward with respect to the main frame. At this time, since the fuel container located on the front side is located outside the range of the trajectory when the fuel container located on the rear side moves in accordance with the deformation, the contact between the pair of fuel containers is avoided. The fuel container is not damaged by the contact between the fuel containers.

  Hereinafter, a saddle-ride type vehicle according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 to 5 show a motorcycle 10 as a saddle-ride type vehicle according to the embodiment. The motorcycle 10 includes a pair of wheels including a front wheel 11 and a rear wheel 12, and a vehicle body 10a to which the pair of wheels are attached. The vehicle body 10a includes a vehicle body frame including a pair of left and right main frames 13a and 13b constituting a main part of the vehicle body 10a and a seat frame 14 connected to the rear portion of the main frames 13a and 13b, and the main frames 13a and 13b. A front fork 15 is provided as a supported front suspension device according to the present invention. The front fork 15 is urged toward the extension side by a suspension spring disposed therein, and is extendable so that the front wheel 11 can move in the vertical direction according to the undulation state of the traveling road surface.

  The front fork 15 is composed of two pipe-like rods assembled with a space left and right, and the front wheel 11 is rotatably supported between the lower ends of the front fork 15. That is, a center shaft (not shown) that supports the front wheel 11 is spanned between both lower ends of the front fork 15, and the front wheel 11 is rotatable about the center shaft. Further, the vicinity of the upper end portion of the front fork 15 is connected to both side portions of a steering shaft (not shown) rotatably installed in the pipe-like support member 16 via connecting members 16a.

  The steering shaft is mounted in the support member 16 so as to be rotatable about the axis of the support member 16, and an upper end portion projects from the support member 16. A handle 17 made of a pair of rod-like members extending in a substantially horizontal direction is connected to the upper end portion of the front fork 15 on the left side and the right side, respectively. For this reason, when the steering wheel 17 is rotated and the steering shaft is rotated in the direction around the axis, the front wheel 11 changes its direction to the left and right around the axis of the steering shaft according to the rotation amount of the steering shaft. In addition, grips 17 a are provided at both left and right ends of the handle 17.

  The grip 17a on the right side of the grip 17a is provided so as to be rotatable in the direction around the axis, and is used as a grip portion for holding by hand, and adjusts the driving force of a driving motor 42 described later. An accelerator operation element is configured. The left grip 17a is fixed to the handle 17 and used as a grip portion for holding by hand. Further, in the vicinity of the grip 17a, a brake lever 18 that is biased away from the grip and that suppresses the rotation of the front wheel 11 or the rear wheel 12 by being pulled toward the grip 17a is provided.

  The main frames 13a and 13b are composed of a pair of left and right symmetric strong frames that are curved in both side view (FIG. 2) and plan view (FIG. 3). The front end portions (upper end portions) of the main frames 13a and 13b are connected to the outer peripheral portion of the support member 16, and the front fork 15 and the handle 17 are supported by the main frames 13a and 13b. The main frames 13a and 13b are formed in an elongated left-right symmetric plate shape having a wide front portion and a gradually narrowing rear portion, and are spaced apart from each other with the width side surfaces facing sideways. Are assembled to the vehicle body 10a. Further, the main frames 13a and 13b are inclined so that the position on the front end side is high and the position on the rear end side is low, and the curved protruding sides are directed upward and laterally, respectively.

  That is, the main frames 13a and 13b are curved so that the distance between the main frames 13a and 13b is widened from the connecting portion to the support member 16 and extends diagonally downward toward the rear, and then the left and right distances are constant. It is curved and extended further obliquely downward while maintaining parallel. And the front-end part of the seat frame 14 is connected with the upper part of the rear part part of both the main frames 13a and 13b. The seat frame 14 is formed of a long and narrow pipe, and a long and narrow U-shaped rear frame 14a fixed to the rear end side portion of the main frames 13a and 13b via a connecting member 19, and the main frames 13a and 13b. It consists of a reinforcing arm 14b that connects the approximate center in the front-rear direction and the approximate center in the front-rear direction of the rear frame 14a.

  Both U-shaped open ends of the rear frame 14a are fixed to the main frames 13a and 13b via a pair of connecting members 19, and both ends of the reinforcing arm 14b are connected to the main frames 13a and 13b and the rear frame 14a. It is fixed to the corresponding part by welding. Further, the rear frame 14a is disposed to be inclined so that the position on the front end side is low and the position on the rear end side is high, and the reinforcing arm 14b is slightly curved so that the center in the front-rear direction protrudes upward. In this state, it is bridged between the main frames 13a and 13b and the left and right side portions of the rear frame 14a.

  In addition, the connection member 19 is comprised by the plate-shaped connection piece, and the rear part of the main frames 13a and 13b and the both open ends of the rear frame 14a are being fixed by welding, respectively. Further, the strength of the seat frame 14 is smaller than the strength of the main frames 13a and 13b. Therefore, when the motorcycle 10 receives a strong impact from the rear, the seat frame 14 is easily deformed upward with respect to the main frames 13a and 13b with the connecting member 19 as a center.

  In addition, underframes 21a and 21b made of L-shaped pipes extending in the rear horizontal direction are provided in parallel at the lower portions of the front side portions of the main frames 13a and 13b. The fuel cell module 22 is supported by the under frames 21a and 21b.

It is comprised with the controller 22B. In addition, a subframe (not shown) is attached between the main frames 13a and 13b, and a plurality of secondary batteries 23 made of lithium ion batteries are arranged in the front-rear direction at the central portion of the upper surface of the subframe. is set up.

  A radiator 24 is attached between a lower portion of the front end side portions of the main frames 13a and 13b and a portion slightly lower than the center of the vertically extending portions of the under frames 21a and 21b via a fixing member 24a. An electric fan 24b for air-cooling the radiator 24 is attached to the back surface of the radiator 24 (the rear surface of the radiator 24). A water pump 25 is attached to the lower side of the radiator 24 between the under frames 21a and 21b. As shown in FIG. 6, the radiator 24 and the fuel cell system 22A are connected by cooling water pipes 26a and 26b, and the water pump 25 is provided in the cooling water pipe 26a.

  That is, the cooling water pipe 26a extends from the radiator 24 to the water pump 25, and further passes through the front surface of the housing portion of the fuel cell module 22 from the water pump 25 and is connected to the internal fuel cell system 22A. Further, between the fuel cell system 22A and the radiator 24, the cooling water that has cooled the fuel cell system 22A is connected by a cooling water pipe 26b that flows from the fuel cell system 22A toward the radiator 24. For this reason, when the water pump 25 is activated, the cooling water in the radiator 24 is sent to the fuel cell system 22A through the cooling water pipe 26a to cool the fuel cell system 22A. Then, the cooling water that has absorbed heat by cooling the fuel cell system 22 </ b> A is returned to the radiator 24 through the cooling water pipe 26 b and is cooled by the electric fan 24 b while passing through the radiator 24.

  In addition, a bowl-like shape in which curved dam portions that are long in the front-rear direction and project outwardly at both front-rear ends are formed in a portion from the upper front end side of the main frames 13a, 13b to the upper front end side of the reinforcing arm 14b.

A hydrogen tank 28a filled with hydrogen to be supplied to the fuel cell system 22A is installed on the upper surface of the tray 27a. A tray 27b having the same shape as the tray 27a is also attached to the upper rear side of the rear frame 14a with the front side being lower than the rear side along the inclination of the rear frame 14a. A hydrogen tank 28b filled with hydrogen to be supplied to the fuel cell system 22A is installed on the upper surface of the tray 27b in the same manner as the hydrogen tank 28a.

  The hydrogen tanks 28a and 28b are composed of the same container and are arranged so as to be symmetrical in the front-rear direction. The hydrogen tank 28a is fixed to the tray 27a by a pair of front and rear bands 29a, and the hydrogen tank 28b is fixed to the tray 27b by a pair of front and rear bands 29b. 6 and 7, the hydrogen tank 28a is connected to the fuel cell system 22A by the gas pipe 31a, the three-way valve 32 and the gas pipe 31, and the hydrogen tank 28b is connected to the gas pipe 31b and the three-way valve 32. And a gas pipe 31 connected to the fuel cell system 22A.

  As shown in FIG. 8 (shown as the hydrogen tank 28a), the hydrogen tanks 28a and 28b are formed of an elongated cylindrical body whose both ends are closed, and the supply according to the present invention is provided at one end. A valve part 33 as a pipe part is provided.

The hydrogen supply port 33e of the hydrogen tank 28a is connected to the gas pipe 31a, and the hydrogen supply port 33e of the hydrogen tank 28b is connected to the gas pipe 31b.

  The gas charging port 33f is an opening / closing port used when there is no residual hydrogen gas in the hydrogen tanks 28a and 28b and the hydrogen gas is newly reinforced, and the connector 33g is connected to the controller 22B and connected to the controller 22B. The electromagnetic valve 33b is operated by the control. The auxiliary valve 33h is for releasing the hydrogen gas in the hydrogen tanks 28a and 28b to the outside when the temperature of the hydrogen tanks 28a and 28b rises or when the pressure becomes higher than a predetermined value. Furthermore, the three-way valve 32 switches the supply source of the hydrogen gas supplied to the fuel cell system 22A between the hydrogen tank 28a and the hydrogen tank 28b by the pressure in the gas pipes 31a and 31b.

  As shown in FIG. 7, the hydrogen tanks 28 a and 28 b have the valve unit 33 configured as described above close to each other and face each other, and the valve unit 33 of the hydrogen tank 28 a is connected to the hydrogen tank 28 b. The valve portions 33 are installed with their positions in the front-rear direction and the up-down direction being shifted so that they are located in the lower front portion of the valve portion 33. Therefore, for example, the motorcycle 10 is rear-projected by another vehicle or the like from the rear, and the rear portion of the seat frame 14 is deformed so as to bend upward with respect to the main frames 13a and 13b, as shown in FIG. It is avoided that the valve portions 33 of the hydrogen tanks 28a and 28b collide with each other.

  That is, due to the deformation of the seat frame 14, the valve portion 33 of the hydrogen tank 28b moves in an arc from the rear upper part of the valve portion 33 of the hydrogen tank 28a upward to the valve portion 33 of the hydrogen tank 28a. It is avoided that both valve parts 33 collide with each other. Further, since the positions of both the valve portions 33 in the front-rear direction and the vertical direction are shifted, it is easy to operate both the valve portions 33. Further, when the hydrogen tanks 28a and 28b are installed, the hydrogen tank 28b is installed after the hydrogen tank 28a is installed, so that both valve portions 33 do not interfere with each other.

For this reason, by the operation of the air compressor 37, the air on the lower side of the seat 34 is sucked through the air element 36 and supplied to the fuel cell system 22A.

  At this time, when the air sucked into the air element 36 passes through the air element 36, the foreign matter is removed. When passing through the fuel cell system 22A, air other than oxygen gas that reacts with hydrogen gas and is used for power generation of the fuel cell system 22A is discharged to the outside. In addition, a rear arm (not shown) including a pair of arm members extending rearward is connected to the rear end portions of the main frames 13a and 13b via a connecting member (not shown).

The water pump 25 operates in response to an operation instruction signal from the control controller 22B, and circulates cooling water between the radiator 24 and the fuel cell system 22A to bring the temperature of the fuel cell system 22A to a predetermined temperature. maintain. The electric fan 24b operates in response to an operation instruction signal from the controller 22B to cool the radiator 24 with air. Boost converter 45 boosts the electricity generated by fuel cell system 22A in response to a voltage instruction signal from controller 22B, and sends it to secondary battery 23 to charge secondary battery 23.

  Further, the DC / DC converter 46 sets the voltage of the current supplied from the secondary battery 23 to a constant and stable voltage and sends it to the inverter 47. The inverter 47 responds to the voltage instruction signal from the controller 22B. The current sent from the DC converter 46 is converted from direct current to alternating current. The drive motor 42 is supplied with an alternating current from the inverter 47, receives an operation signal corresponding to the operation amount of the grip 17a constituting the accelerator operation element from the controller 22B, and operates according to the operation signal. .

  Further, the control controller 22B includes a CPU, a RAM, a ROM, a timer, and the like, and various programs prepared in advance and data such as maps are stored in the ROM. Then, the CPU controls each device such as the drive motor 42, the electromagnetic valve 33b, the air compressor 37, and the water pump 25 based on the operation of the grip 17a and the like by the driver and a program prepared in advance. Further, the motorcycle 10 is in a state where the controller 22B starts to operate and can run by turning on the main key switch 48. The surface of the vehicle body 10a of the motorcycle 10 is covered with a cover member (not shown) so that the inside cannot be seen.

  In this configuration, when the motorcycle 10 is operated, the hydrogen tank 28a is installed in the tray 27a in advance, and the hydrogen tank 28b is installed in the tray 27b in advance. In this case, first, the hydrogen tank 28a is installed, and then the hydrogen tank 28b is installed, so that the hydrogen tanks 28a and 28b can be installed without causing interference between the valve portions 33 of the hydrogen tanks 28a and 28b. Yes. Next, the hydrogen supply port 33e of the hydrogen tank 28a is connected to the three-way valve 32 via the gas pipe 31a, and the hydrogen supply port 33e of the hydrogen tank 28b is connected to the three-way valve 32 via the gas pipe 31b. Then, both open / close valves 33d of the hydrogen tanks 28a and 28b are opened, and for example, the hydrogen tank 28a is connected to the fuel cell system 22A.

  In this state, the driver sits across the seat 34. In this case, the driver can easily board and maintain a comfortable seating posture. Next, the main key switch 48 is turned on. As a result, air is supplied to the fuel cell system 22A from the air compressor 37 and hydrogen is supplied from the hydrogen tank 28a. The fuel cell system 22A reacts oxygen and hydrogen in the supplied air to generate electricity. Is generated. By operating the grip 17a and the handle 17 in this state, the motorcycle 10 can be driven in a predetermined direction at a predetermined speed. Then, when traveling for a predetermined distance and the remaining amount of hydrogen in the hydrogen tank 28a decreases, the electromagnetic valve 33b is closed and the hydrogen tank 28a side is closed, and the electromagnetic valve 33b of the hydrogen tank 28b is opened and the hydrogen tank 28a is opened. Hydrogen gas is supplied from the tank 28b to the fuel cell system 22A. The hydrogen tank 28a is replaced with another hydrogen tank that is fully filled with hydrogen gas at an appropriate time.

  As described above, in the motorcycle 10 according to the present embodiment, the pair of hydrogen tanks 28a and 28b are mounted on the vehicle body 10a side by side with the longitudinal direction thereof facing forward and backward. For this reason, even if the two hydrogen tanks 28a and 28b are mounted on the motorcycle 10, the vehicle width can be prevented from increasing, and the weight balance between the front and rear of the motorcycle 10 can be improved. Further, in the motorcycle 10, the hydrogen tanks 28a and 28b are arranged with the valve portions 33 facing each other and the valve portions 33 being close to each other. For this reason, the length of gas piping 31a, 31b which connects between each valve part 33 and the three-way valve 32 can be shortened.

  Furthermore, since the hydrogen tanks 28a and 28b are arranged so as to shift the positions of both the valve portions 33 in the vertical direction and the front-rear direction, it is possible to prevent the two valve portions 33 from interfering with each other. Further, since the hydrogen tanks 28a and 28b are brought close to each other so that the valve portions 33 overlap each other, the mounting space in the front-rear direction of the motorcycle 10 occupied by the hydrogen tanks 28a and 28b is lengthened accordingly. Can be from the center without. Further, the seat 34 is disposed above the mutually opposing portions of the pair of hydrogen tanks 28a and 28b arranged along the inclination of the main frames 13a and 13b whose rear side is lowered and the rear frame 14a whose front side is lowered. Therefore, it is not necessary to increase the height of the sheet 34. As a result, the ease of getting on and off the motorcycle 10 is improved.

  In the motorcycle 10 according to this embodiment, the hydrogen tank 28a is attached to the main frames 13a and 13b, and the other hydrogen tank 28b is attached to the rear frame 14a of the seat frame 14. Therefore, the weights of the pair of hydrogen tanks 28a and 28b can be dispersed and supported by the main frames 13a and 13b and the seat frame 14, and the weights of the hydrogen tanks 28a and 28b are concentratedly loaded on one frame. I'm sorry. Further, since the valve portions 33 of the hydrogen tanks 28a and 28b are disposed between the rod-like portions on both sides of the rear frame 14a in the seat frame 14 and between the pair of reinforcing arms 14b, both the valve portions 33 are protected by the seat frame 14. can do.

  Further, in the motorcycle 10 according to the present embodiment, when the rear portion of the seat frame 14 is deformed upward with respect to the main frames 13a and 13b due to an external force caused by a rear-end collision of the following vehicle, hydrogen is generated along with the deformation of the seat frame 14. The hydrogen tank 28a fixed to the main frames 13a and 13b is positioned outside the range of the locus when the tank 28b moves. For this reason, it is avoided that the hydrogen tanks 28a and 28b contact each other, and the hydrogen tanks 28a and 28b are not damaged by the contact between the hydrogen tanks 28a and 28b.

  Further, the saddle-ride type vehicle according to the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above-described embodiment, the saddle-ride type vehicle is the motorcycle 10. However, the saddle-ride type vehicle is not limited to the motorcycle, and may be a vehicle such as an automatic tricycle, an automatic four-wheel vehicle, or a snow vehicle. Also good. In the above-described embodiment, the three-way valve 32 is switched by the pressure in the gas pipes 31a and 31b. The three-way valve 32 is one of the hydrogen tanks 28a and 28b in which hydrogen gas is used. When the remaining amount of hydrogen gas becomes small, it may be operated according to a switching instruction signal from the controller 22B and switched to the other. Furthermore, other parts constituting the saddle-ride type vehicle according to the present invention can be appropriately changed within the technical scope of the present invention.
