Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The ignition switch device according to this embodiment is for controlling engine start and stop in a two-wheeled vehicle. As shown in FIGS. 1 and 2, a cylinder body 1 that constitutes a main body of the ignition switch device, and an antenna 3. Are mainly composed of a cap portion 2 including a housing portion 12 including a circuit board 4, and a conductive wire 5 electrically connecting the antenna 3 and the circuit substrate 4.

  As shown in FIG. 1, the cylinder body 1 includes a rotor 7 that can be rotated by inserting a key K, an actuator 13 that can rotate in conjunction with the rotor 7, and a protruding state of a handlebar (not shown). A lock bar 8 that can be engaged with the rotation shaft to lock the handle bar, a fixed terminal 10 and a movable terminal 11 are included. The rotor 7 is configured such that a plurality of tumblers are arranged at regular intervals in the axial direction, and can rotate around the axis only when a key K corresponding to the tumblers is inserted.

  Accordingly, when the key K is rotated from the off position to the locked position and the rotor 7 is rotated in a predetermined direction, the actuator 13 rotates in the same direction, and the lock bar is connected via the cam portion 9 integrated with the actuator 13. The handle bar can be locked by protruding 8. On the other hand, when the key K is rotated from the off position to the on position and the rotor is rotated in a predetermined direction, the movable terminal 11 is rotated via the actuator 13 and the cam portion 9, and a fixed contact (not shown) of the fixed terminal 10 is also shown. ) And the movable contact 11a of the movable terminal 11, a predetermined circuit is formed so that the engine (not shown) of the motorcycle can be started.

  Incidentally, a transponder 6 as a transmitting means is disposed in the gripping portion Ka of the key K, and constitutes a so-called immobilizer together with an antenna 3 and a circuit board 4 described later. Here, the immobilizer refers to the transponder by comparing the data communication result of the code obtained by encrypting the key number (vehicle-specific ID code) stored in the transponder 6 and the key number stored in advance on the vehicle side. This means that the engine is allowed to start on condition that the ID code from 6 is determined to be registered in advance.

  That is, the ID code transmitted from the transponder 6 is received by the antenna 3 and sent to the circuit board 4 through the conductive wire 5, and signal processing such as amplification processing is performed on the circuit board 4. Then, the ID code subjected to signal processing on the circuit board 4 is sent to, for example, an ECU (engine control device) or the like provided in the vehicle to determine whether or not the ID code is registered in advance. If it is, the engine is allowed to start, while if not, the engine is not allowed to start even if the key K is rotated to the ON position.

  The circuit board 4 is connected to the tip of the conductive wire 5 and is formed with a circuit for processing the ID code received by the antenna 3 as described above. Molded by filling with resin. The circuit board 4 is also electrically connected to the above-described ECU, and is configured to transmit the signal-processed ID code to the ECU.

  However, the interior of the accommodating portion 12 is divided into an upper side and a lower side, the circuit board 4 is disposed on the lower side, and a sliding surface that can rotate the movable terminal 11 is formed on the upper side. ing. In this embodiment, the ECU is configured so that the identification (collation) of the ID code received by the antenna 3 is performed by the ECU. For example, the circuit board 4 is provided with a function of identifying the ID code, Accordingly, an engine start permission signal (or non-permission signal) may be transmitted to the ECU.

  On the other hand, on the outer wall surface of the cylinder body 1, as shown in FIG. 3, a groove shape 1 a that extends from the upper end side to the lower end side of the cylinder body 1 and that can be guided by inserting the conductive wire 5 is formed. It is included. That is, the conductive wire 5 extends from the antenna 3 in the cap part 2 to the circuit board 4 in the housing part 12 while being guided by the groove shape 1a, so that the antenna 3 and the circuit board 4 are electrically connected. It has become.

  As shown in the figure, the groove shape 1a is composed of a concave groove opened to the side of the cylinder body 1, and is assembled in a state in which the conductive wire 5 is inserted and fitted into the concave groove. . Thereby, the conductive wire 5 is disposed through the outside of the cylinder body 1, and the workability at the time of assembling the ignition switch can be improved as compared with the case where the conductive wire 5 is passed through the cylinder body 1. In addition, since the groove shape 1a is opened to the side, the front side (front side as viewed from the direction A in the figure) is blocked and the conductive wire 5 is hidden, thereby preventing mischief and the like on the conductive wire 5. be able to.

  The cap part 2 includes an outer cylinder part 2a, an intermediate cylinder part 2b, and an inner cylinder part 2c. The cap part 2 is attached to the upper end side of the cylinder body 1 while holding the antenna 3 between the outer cylinder part 2a and the intermediate cylinder part 2b. ing. An antenna 3 is insert-molded at the upper end of the middle cylinder portion 2b, and a protruding portion 2ba protruding downward is integrally formed. The protruding portion 2ba includes the proximal end side of the conductive wire 5. The protruding portion 2ba (same for the entire middle tube portion 2b) is made of a predetermined resin material having flexibility, and when the cap portion 2 is attached to the cylinder body 1, the proximal end side of the included conductive wire 5 is grooved.
