Abstract: A vehicle front structure that reduces a shock load applied to immediately under a front grille by using a bumper beam as a support. A vehicle front structure includes a shock absorbing member at an interior of a bumper face on the side near an upper portion thereof which absorbs a load from the diagonally upper front side. The shock absorbing member is at the interior of the bumper face below a front grille, and includes a load receiving portion that receives a load, a locking portion locked to an upper end edge of a bumper beam located behind and below the load receiving portion, at the time of receding of the shock absorbing member, and a connecting portion connecting the load receiving portion and the locking portion. A deformation facilitating portion with respect to a load from the upper front side is thus configured at the connecting portion.

Abstract: An increased amount of absorption of a load from the diagonally upper front side is achieved even in, for example, a vehicle having a high vehicle height. A first shock absorbing member is provided inside a bumper face upper to absorb a load from the diagonally upper front side, a second shock absorbing member is mounted on a front face portion of a bumper beam, and a third shock absorbing member is disposed below the first shock absorbing member and between a bumper face and the bumper beam to absorb a load from the diagonally upper front side. The rigidity of the first and third shock absorbing members in the up-down direction is higher than rigidity of the second shock absorbing member in the front-rear direction.
