Abstract

A vehicle body front structure includes a front side member that is arranged on a side portion of a vehicle body front portion and extends in a vehicle body front-rearward direction; an extending portion that extends farther toward an outside in a vehicle width direction than the front side member; and a load transmitting member that connects the extending portion and the front side member together, and is configured such that a pushing portion on a front end side is guided toward a receiving portion on a rear end side by an intermediate portion deforming in response to a frontal collision load.

First claim

What is claimed is:

1. A vehicle body front structure comprising:
a front side member that is arranged on a side portion of a vehicle body front portion, and extends in a vehicle body front-rearward direction;
an extending portion that extends farther toward an outside in a vehicle width direction than the front side member;
a load transmitting member that connects the extending portion and the front side member together, and is configured such that a front end side of the load transmitting member is guided toward a rear end side of the load transmitting member by an intermediate portion of the load transmitting member deforming in response to a load toward a rear side in the vehicle body front-rearward direction, the load transmitting member is a closed sectional structure, wherein
a weak portion that becomes a starting point for deformation is formed on a portion on the outside, in the vehicle width direction, of the intermediate portion of the load transmitting member;
a receiving portion is provided on the rear end side of the load transmitting member;
a pushing portion that is guided toward the receiving portion is provided on the front end side of the load transmitting member, the pushing portion pushing the receiving portion toward an inside in the vehicle width direction; and
the receiving portion and the pushing portion are a reinforcing member provided inside the load transmitting member.

2. The vehicle body front structure according to claim 1 , wherein
the rear end side of the load transmitting member is positioned to the rear side in the vehicle body front-rearward direction, and to an inside in the vehicle width direction, with respect to the front end side of the load transmitting member.

3. The vehicle body front structure according to claim 1 , wherein
the extending portion is provided on a bumper reinforcement that is arranged on a vehicle body front end side and extends in the vehicle width direction.

4. A vehicle body front structure comprising:
a front side member that is arranged on a side portion of a vehicle body front portion, and extends in a vehicle body front-rearward direction;
an extending portion that extends farther toward an outside in a vehicle width direction than the front side member;
a load transmitting member that connects the extending portion and the front side member together, a weak portion that becomes a starting point for deformation being formed on a portion on an outside, in the vehicle width direction, of an intermediate portion of the load transmitting member, the load transmitting member is a closed sectional structure;
a receiving portion is provided on the rear end side of the load transmitting member;
a pushing portion that is guided toward the receiving portion is provided on the front end side of the load transmitting member, the pushing portion pushing the receiving portion toward an inside in the vehicle width direction; and
the receiving portion and the pushing portion are a reinforcing member provided inside the load transmitting member.

5. The vehicle body front structure according to claim 4 , wherein
the extending portion is provided on a bumper reinforcement that is arranged on a vehicle body front end side and extends in the vehicle width direction.
