BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a vehicle headlamp fixing structure according to an embodiment of the present invention. As shown in FIGS. 1 and 2, a front underrun protector 8 is supported via a protector bracket 9 on a chassis frame 11 reinforced with high rigidity by a cross member 12 and the like. Front underrun protector 8
Is made of a highly rigid member having a width dimension corresponding to the lateral width of the vehicle, and is disposed in a space between the lower surface of the cab 13 and the ground, and prevents other objects or the like from getting into the space.

As shown in FIG. 1, the width of the front underrun protector 8 is equal to the width of the left and right chassis frames 11 and 11.
The front underrun protector 8 is considerably overhanged from the side of the chassis frame 11 because it is much wider than the width between the two. Therefore, the portion of the overhanging front underrun protector 8 has lower bending rigidity than the portion near the center. In order to increase the bending rigidity of this portion, means for connecting both ends of the front underrun protector 8 and the chassis frames 11 and 11 with rigid members (not shown) may be employed. As the rigid member, for example, a member in which a rigid body or the like is erected between a step (not shown) fixed to the side surface of the chassis frame 11 and an end of the front underrun protector 8 is employed.

As shown in FIG. 1, a bumper 7 is integrally disposed below the front surface of the cab 13, and a head lamp portion 6a with which the head lamp 6 is engaged is formed.
The headlamp 6a may be covered by a cover (not shown) provided on the bumper 7 side. The headlamp 6 is disposed substantially above the front underrun protector 8 in a state of being engaged with the headlamp section 6a. Therefore, the headlamp 6 can be fixed to the front underrun protector 8 via the fixture.

An embodiment of a fixture for holding the headlamp 6 will be described. 1 to 3 show a case where a rod member 1 is used as the fixture. The rod member 1 is formed by bending a pipe material or a rod material into an inverted U-shape that can be wound around the outer contour of the headlamp 6. Both ends of the rod member 1 can be fastened to the front underrun protector 8 side, for example. A screw is formed. As shown in the figure, the rod member 1 having the above shape is wound around the outer contour of the headlamp 6, and the fastener 10 fixed to the headlamp 6 is fixed to the rod member 1. Next, the head lamp 6 is securely fixed to the front under-run protector 8 via the rod member 1 by inserting both ends of the rod member 1 into the front under-run protector 8 and fastening the screws. The rod member 1 may have a shape capable of winding the outer contour of the headlamp 6 as described above, and is much simpler and lighter than the conventional mounting device 14 shown in FIG.
It is formed at low cost. Further, as described above, since the headlamp 6 is securely fixed to the front underrun protector 8, the headlamp 6 does not swing even when the vehicle is running. Further, the assembling and removing of the rod member 1 is extremely easy, and the assembling workability can be improved.

FIG. 4 shows another embodiment of the fixing device. In this example, a support 2 is used as the fixing tool. That is, the support table 2 is
Is provided between the lower surface of the front lamp and the front underrun protector 8, and the upper surface and the lower surface thereof have a shape that can be in close contact with the headlamp 6 and the front underrun protector 8. Although the headlamp 6 is stably supported only by supporting the headlamp 6 on the support base 2, in order to further ensure the support of the headlamp 6, for example, as shown in FIG. The headlamp 6 is fixed to the support 2 by inserting the screw 3 into the support 2 and tightening the screw with a nut 4 or the like. This support 2 is attached to a front underrun protector 8.
, The head lamp 6 is securely fixed to the front underrun protector 8. This support 2
