Furthermore, since the shock absorber support chambers of the present invention are located at the rear left and right corners of the luggage compartment, which are difficult to see from the outside, they are hardly noticeable and the appearance can be improved accordingly.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 are diagrams for explaining a shock absorber support structure for a rear wheel suspension system for an automobile according to an embodiment of the present invention. In the figure, 1 is a luggage compartment formed at the rear end of the vehicle body, and the luggage compartment 1 has a floor 2 constituting a bottom wall, a rear panel 3 constituting a rear wall,
It is constructed by assembling together a side panel 4 forming a side wall by welding.

Left and right rear wheel houses 5 are disposed on the left and right sides of the luggage compartment 1, and a rear wheel 6 is disposed within the rear wheel houses 5. This rear wheel 6
is rotatably supported by an axle (not shown) fixed to the tip of a suspension arm 7 that is approximately A-shaped in plan view, and this suspension arm 7 is swingably supported by the vehicle body. . Further, the rear wheel house 5 is made up of an outer panel 8 that is bulged toward the outside of the vehicle interior, and an inner panel 9 that is bulged toward the cargo compartment 1 side. It is fixed by spot welding and is attached to the upper side 9a of the inner panel 9.
is fixed to the side panel 4, and the lower side portion 9b is fixed to the floor 2 and frame 2a by spot welding.

The inner panel 9 is formed into a roughly semicircular shape when viewed from inside the cargo compartment 1, and the rear portion 9c of the panel 9 extends toward the rear of the vehicle at approximately 1/2 the height of the inner panel 9. , and bulges inside the luggage compartment 1. The rear end flange portion 9d of this rear portion 9c,
9e is fixed to the corner portion of the rear panel 3 and side panel 4 by spot welding,
In this way, the rear part 9c of the inner panel 9, the rear panel 3, and the side panel 4 form the shock absorber support chamber 10.
is formed.

Further, a reinforcing plate 11 having a shape along the inner panel 9 is arranged on the vehicle outer side of the shock absorber support chamber 10, and the upper end 11a of the reinforcing plate 11 is inserted between the inner panel 9 and the side panel 4. The lower part 11b is welded and fixed to the lower part 9b of the inner panel 9. Further, a support portion 11c is formed at the upper part of the reinforcing plate 11 by bending the portion outward, and the ring-shaped upper end attachment portion 12a of the shock absorber 12 is attached to the attachment bolt 13 by the support portion 11c. Supported through. Further, the shock absorber 12 is arranged diagonally at an angle of approximately 45 degrees so that the upper end mounting portion 12a is located at the rear of the vehicle, and the ring-shaped lower end mounting portion 12b formed at the lower end is connected to a mounting bolt (not shown). It is supported by the suspension arm 7 via the suspension arm 7.

Next, the effects of this embodiment will be explained.

If the upper end of the shock absorber is supported by an inner panel that is formed in a bulge on the inside of the cargo compartment, in the conventional structure described above, the shock absorber support chamber is formed in a bulge in the center of the inner panel. The problem was that the bulging portion narrowed the effective space in the luggage compartment and also degraded the appearance. On the contrary,
In this embodiment, the rear part 9c of the inner panel 9 is extended rearward and bulged inward, and the extended bulge is connected to the corner of the rear panel 3 and the side panel 4 to support the shock absorber. Since the chamber 10 is formed, the support chamber 10 is located in the corner of the luggage compartment 1, which is a dead space that has not been used much in the past.Therefore, in this embodiment, the shock absorber support chamber 10 narrows the luggage compartment space. Compared to conventional structures, the effective space in the luggage compartment can be expanded. Furthermore, in this embodiment, the shock absorber support chamber 10 is formed behind the inner panel 9, and the shock absorber 12 is arranged diagonally, so that the shock absorber support chamber 10 is approximately half the size of the conventional support chamber. It only requires a little height, and from this point of view you can also expand the cargo space.

In addition, since the shock absorber support chamber 10 of this embodiment is located in a corner part of the luggage compartment 1 that is not easily visible from the outside, the conventional support chamber is located in the center of the inner panel and, by extension, in the center of the luggage compartment. There is no problem of it bulging out and making it stand out, and the appearance can be improved accordingly. Moreover, in this embodiment, the upper end mounting portion 12 of the shock absorber 12
Since the upper end mounting portion 12a is supported by the reinforcing plate 11 disposed on the outside of the vehicle, the upper end mounting portion 12a does not bulge toward the inside of the vehicle, and the appearance can be improved from this point as well.

In the above embodiment, the upper end mounting portion 12a of the shock absorber 12 is supported on the outside of the vehicle to prevent the mounting portion 12a from protruding toward the inside of the vehicle. However, in the present invention, such support is not necessarily required. It is not necessary to adopt this structure, and a structure may be adopted in which the upper end mounting portion faces the passenger compartment. Even in this case, since the shock absorber support chamber is located at the corner of the luggage compartment, the effective space of the vehicle compartment can be expanded and the appearance can be improved.

[Effect of idea]

As described above, according to the support structure of the rear wheel shock absorber according to the present invention, the rear part of the inner panel of the rear wheel house is extended rearward and bulged inside the cargo compartment to form the shock absorber support chamber. Therefore, the shock absorber support chamber is located in the corner of the luggage compartment, which was conventionally a dead space, which allows for more effective use of space, which has the effect of expanding the luggage compartment space, and also makes the shock absorber support chamber less noticeable. , it has the effect of improving the appearance.
