Further, the displacement allowing portion 55 is formed by a concave portion 56 that is open at the front side of the vehicle. This concave-shaped portion 56 is formed by integrally connecting an upper wall 56a, a rear wall 56b, and a lower wall 56c in a concave shape, and the upper wall 56a and the lower wall 56c are displaced when the above-mentioned elements 31c and 32 are displaced upward. It is a replacement.

Incidentally, if the lower attachment piece 35 and the rear end of the connecting portion 31e are linearly connected as shown by the imaginary line β in FIG. 32, it becomes difficult to secure a sufficient amount of displacement during upward displacement.

By forming the displacement allowing portion 55 on the lower mounting piece 35, the displacement allowing portion 55 absorbs impact against the sensor protection bracket 53 located at the rear of the impact absorbing member 30 in the event of a minor vehicle collision. The sensor protection bracket 53 is configured to be prevented from being damaged by allowing the member 30 to be displaced upward.
Furthermore, at the same time, the displacement allowing part 55 of the lower mounting piece part 35 is structured to be separated from the front side of the connecting part 31e via the separating part 34, and furthermore, after extending rearward from the connecting part 31e (upward Since the wall 56a) is configured to extend downward (rear wall 56b), it is possible to suppress the influence when an impact load is input to the load receiving portion and the connecting portion 31e deforms to absorb the impact load. Note that the upper wall 56a of the displacement allowing portion 55 may be formed to extend rearward from the lower end of the load receiving portion 31c, for example.

That is, the shock absorbing member 30 includes a locking portion 31d that is locked to the upper end edge portion 4e of the bumper beam 4 located rearward and downward with respect to the load receiving portion 31c when the shock absorbing member 30 retreats, and A connecting portion 31e connects the portion 31c and the locking portion 31d, and the lower mounting piece portion 35 extends rearward from the front side of the load receiving portion 31c or the connecting portion 31e via the separating portion 34. After extending, it extends downward.
As a result, since the lower mounting piece 35 is structured to be separated from at least the front side of the connecting portion 31e, when an impact load is input to the load receiving portion 31c and the connecting portion 31e deforms to absorb the impact load. It is possible to suppress the influence of

As shown in FIG. 13, at the lower end of the upper mounting piece 32 and at the rear end of the upper piece 31f, the shock absorbing member 30 is displaced upward when it comes into contact with the rear sensor protection bracket 53. A sloped surface portion 31n is formed.

This inclined surface portion 31n is a so-called tapered surface portion that is inclined in a manner that the front part is low and the rear part is high. It is formed in a position opposite to. Specifically, the inclined upper portion of the inclined surface portion 31n faces the front end corner portion 53c.

When the shock absorbing member 30 retreats and the inclined surface portion 31n comes into contact with the front end corner portion 53c during a light vehicle collision, the shock absorbing member 30, especially its upper mounting piece 32, moves along the slope of the inclined surface portion 31n. and displaces the upper piece portion 31f upward. The structure is designed to reduce the load applied to the sensor protection bracket 53, which is a structural body, due to the upward displacement of the shock absorbing member 30 by the inclined surface portion 31n.

As shown in FIG. 13, the lower attachment piece 35 described above extends downward from the lower end of the load receiving portion 31c via the connecting portion 31e and the concave portion 56 extending rearward. On the other hand, the above-mentioned upper attachment piece 32 extends upward from the upper end of the load receiving part 31c via the upper piece 31f and the inclined surface 31n that extend rearward.

Here, the length of the upper piece portion 31f in the vehicle longitudinal direction is longer than the length of the connecting portion 31e in the vehicle longitudinal direction. In other words, the lower attachment piece 35 extends rearward and downward from the load receiver 31c, while the upper attachment piece 32 extends rearward from the load receiver 31c and then upward.

This structure suppresses the influence of the upper mounting piece 32 on the load receiving portion 31c.
Furthermore, as described above, the above structure is installed in the sensor protection bracket 53 provided on the back side of the front grille 8, thereby protecting the airbag sensor 54 and preventing damage to the sensor protection bracket 53 in the event of a light collision. The structure is designed to achieve both prevention and prevention.

Additionally, as shown in FIG. 4, an emblem 10 is disposed in front of the front grille 8 to which the above-mentioned upper attachment piece portion 32 is attached, that is, in front of the center of the front grille 8 in the vehicle width direction. Further, the lower attachment piece 35 is attached to the lower grill 9 as a lower grill member located at the rear of the lower part of the bumper face 7, that is, on the lower back side of the bumper face 7.

As a result, the mounting members for attaching the upper and lower mounting pieces 32 and 35 are not visible from outside the front side of the bumper face 7, and the mounting members for attaching the upper and lower mounting pieces 32 and 35 to the bumper face surface are no longer visible. The structure is designed to prevent damage and ensure good appearance.

As described above, the vehicle front structure of the above embodiment is a vehicle front structure in which the shock absorbing member 30 for absorbing the load from diagonally above the front is provided inside the bumper face 7 near the upper part. The shock absorbing member 30 is disposed inside the bumper face 7 below the front grill 8, and the shock absorbing member 30 includes a load receiving portion 31c located forward of the front grill 8 and receiving a load; A lower mounting piece 35 extends rearward from the load receiving portion 31c and is attached to the lower part of the bumper face 7, and a lower mounting piece 35 extends rearward from the load receiving portion 31c and then extends upward. 31c, and a structure (see sensor protection bracket 53) is disposed adjacent to the rear of the upper mounting piece 32. The lower mounting piece 35 is formed with a displacement allowing part 55 that allows upward displacement of the load receiving part 31c and the upper mounting piece 32 when a load is input (FIGS. 3 and 4). , see Figure 13).

According to this configuration, in the event of a light collision of a vehicle, the displacement permitting portion 55 displaces the shock absorbing member 30 upward with respect to the structure behind the shock absorbing member 30 (see sensor protection bracket 53). Damage to the structure (sensor protection bracket 53) can be prevented.

Further, in an embodiment of the present invention, the lower end of the upper mounting piece 32 is provided with the shock absorbing member 30 so that the shock absorbing member 30 is attached to the lower end when it comes into contact with a structure (sensor protection bracket 53) that is a rear vehicle component. An inclined surface portion 31n for displacement is formed (see FIG. 13).
