Abstract

In a vehicle body front structure, a collision load is input to an outside protruding portion of a gusset when a portion farther to a vehicle width direction outside than a front side member of a vehicle collides in a frontal collision with a colliding object (here, barrier (B)) such as an oncoming vehicle (i.e., when a so-called small overlap collision occurs). This gusset is fixed in a cross section of a front portion of the front side member, so the collision load is able to be better transmitted to a vehicle width direction inside portion of the front side member. Moreover, this gusset abuts against a front end portion of the outer panel of the front side member from a vehicle front side, so the collision load is also able to be better transmitted to a vehicle width direction outside portion of the front side member.

First claim

The invention claimed is:

1. A vehicle body front structure of a vehicle comprising:
a front side member that extends in a vehicle longitudinal direction on a side portion of a vehicle body front portion, and an outside open portion that is open outward from a center of the vehicle in a vehicle width direction is formed on a front portion of the front side member;
a load transmitting member that is fixed in an interior of the front portion of the front side member, and the load transmitting member includes an outside protruding portion that passes through the outside open portion and protrudes toward the vehicle width direction, the load transmitting member abutting against a first side wall of the front side member from a vehicle front side;
a bumper reinforcement that extends in the vehicle width direction on a front end portion of a vehicle body of the vehicle; and
a crush box that is formed weaker in the vehicle longitudinal direction than the front side member, and connects the front side member to the bumper reinforcement, and on which an outside extending portion that is positioned in front of the outside protruding portion in the vehicle longitudinal direction is provided.

2. The vehicle body front structure according to claim 1 , wherein
the front side member includes an inner panel with an open sectional shape that is open outward from the center of the vehicle in the vehicle width direction when viewed from the vehicle longitudinal direction, and the front side member includes an outer panel that is connected to the inner panel; and
the outside open portion is formed by a front end portion of the outer panel being positioned farther to a vehicle rear than a front end portion of the inner panel, and the front end portion of the outer panel abuts against a rear surface of the load transmitting member that is fixed in the interior of the inner panel.

3. The vehicle body front structure according to claim 1 , wherein
the load transmitting member has an inside fixed portion that is fixed to a second side wall of the front side member.

4. The vehicle body front structure according to claim 1 , wherein
a rear surface of the load transmitting member is inclined a vehicle rear side of the vehicle farther toward the center of the vehicle in the vehicle width direction.

5. The vehicle body front structure according to claim 2 , wherein
the load transmitting member is fixed to a second side wall of the front side member, or to an upper wall and a lower wall of the inner panel.

6. The vehicle body front structure according to claim 1 , wherein the first side wall of the front side member is farther away from the center of the vehicle in the vehicle width direction than a second side wall of the front side member.

7. The vehicle body front structure according to claim 5 , wherein the first side wall of the front side member is farther away from the center of the vehicle in the vehicle width direction than the second side wall of the front side member.
