[0017]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a front end module 9 is arranged at the front end of the vehicle body so as to connect left and right fenders (not shown), and above the front end module 9. The hood 4 is provided.

The radiator core support 1 for supporting the front end module 9 is integrally molded of a resin such as FRP, and an opening 13 for supporting a radiator core (not shown) is formed at a substantially central portion in the vehicle width direction. 1
3 is formed through.

Through holes 14, 14 for locking the radiator core support 1 to a front fender (not shown) are formed on the upper surfaces of both ends in the vehicle width direction. Bolts (not shown) inserted through these through holes 14 are formed. Thus, the radiator core support 1 is fixed to the vehicle body.

Headlamp housings 10 and 1 as predetermined recesses opened toward the front of the vehicle body at both ends in the vehicle width direction of the radiator core support 1 which is the front end portion of the vehicle body.
0 is formed, and a peripheral portion of the headlamp housing 10 is provided so as to project toward the front of the vehicle body, and a lens retainer 11 that supports the headlamp lens 3 is formed on an end surface of the peripheral portion.

This lens retainer 11 is formed of a convex portion 11B protruding toward the outer periphery and a groove portion 11A which fits with the headlamp lens 3, and the headlamp lens 3 and the radiator core support 1 are joined together. This is done via the clip 5 as a means.

The clip 5 is composed of an elastic member having a substantially "Ω" -shaped cross section, one end 5A of which is engaged with the convex portion 11B, and the other end 5B of which is engaged with the headlamp lens 3 side. With headlamp lens 3 and lens retainer 1
1, i.e. to the radiator core support 1.

A reflector 31 and a bulb 32 are housed inside the headlamp housing 10, and the bulb 32 is fixed to the headlamp housing 10 by a holder 34 coupled from the rear side of the vehicle body.

Below the headlamp housings 10 and 10, there is provided an upright retainer 12 as a bumper retainer, which is provided so as to project substantially horizontally toward the front of the vehicle body, in the vehicle width direction, and the front end of the upward retainer 12 is a lens. Retainer 1
It projects from the front end of 1 to the front of the vehicle body.

A tongue portion 12A is also provided at a predetermined length above the upper retainer 12 projecting forward and below the headlamp housing 10 toward the front of the vehicle body. A groove 12B is formed between the upper retainer 12 and the upper end of the bumper 2,
The bumper 2 fitted in the groove portion 12B is restrained from being displaced in the vehicle width direction by the upper retainer 12 and supported, and further is restrained from being displaced in the vertical direction and the rearward direction of the vehicle by the groove portion 12B so that the bumper 2 has a predetermined position relative to the radiator core support 1. The bumper 2 is coupled to the radiator core support 1 by fastening means (not shown).

Notches 12C and 12C are formed on the upper retainer 12 and the tongue portion 12A at predetermined positions facing the lens retainers 11 and 11 disposed above.
The cutout portion 12C has a predetermined width (vehicle width direction) and depth (vehicle body front-rear direction), and during maintenance work, the worker attaches and detaches the clip 5 and the headlamp lens 3 through the cutout portion 12C. The lower surface of can be grasped.

With the above construction, the operation will be described.

As in the prior art example, the radiator core support 1 is assembled in a sub-line in a process different from the main line, and since the headlamp housing 10 is molded integrally with the radiator core support 1, the reflector 31 is formed. The position where the bulb 32 and the bulb 32 are assembled to the headlamp housing 10 can be a predetermined optical axis position.

Then, the clip 5 with the headlamp lens 3 fitted in the groove 11A of the lens retainer 11 is used.
By assembling the convex portion 11A and the headlamp lens 3 via the headlamp lens 3, the assembly process around the headlamp can be simplified, and in inspection and maintenance of the completed vehicle, the clip 5 can be simply removed. The lamp lens 3 can be attached and detached, and maintainability can be improved.

When replacing the headlamp lens 3 due to damage or the like, the bumper 2 is replaced by the bumper retainer 1.
When the headlamp lens 3 is detached from the headlamp lens 3 or moved forward, the operator can attach and detach the clip 5 and grasp the lower surface of the headlamp lens 3 through the notch 12C provided in the bumper retainer 12. The replacement work can be performed easily and quickly, and the maintainability can be improved.

In the headlamp unit 33 as shown in the conventional example, since the headlamp housing 30 is constructed separately from the radiator core support, the optical axis adjustment of the headlamp is indispensable. By integrally molding with the radiator core support 1, it is possible to absorb the error in the relative position and eliminate the need for adjusting the optical axis of the headlamp.

Next, the assembling of the bumper 2 to the radiator core support 1 is carried out through the uppertainer 12,
The displacement of the bumper 2 in the vehicle width direction is regulated by the upper retainer 12, and the displacement of the bumper 2 in the vertical direction and rearward of the vehicle body is regulated by the groove portion 12B. Therefore, the bumper 2 can be easily positioned with respect to the radiator core support 1 and the headlamp. It can be done.

In addition to the above, the radiator core support 1 is provided with an air plate 6 for guiding intake air to an air cleaner, a radiator grill (not shown), a bonnet lock, etc., to form a front end module 9.

In this way, the optical axis and the building position can be set at predetermined positions simply by assembling the headlamp lens 3 and the bumper 2 to the radiator core support 1, and the front end module 9 assembled in the sub-line is It is mounted on a vehicle body (not shown) in the main line, and a radiator or a condenser (not shown) is further mounted on the opening 13 of the radiator core support 1 to form the front end portion of the vehicle body, and the optical axis of the headlamp lens 3 and the bumper 2 are installed. It is possible to reduce the position adjustment process from the sub line or main line,
By shortening the assembly process of the radiator core support 1, the productivity can be improved.
