VEHICLE FRONT BODY STRUCTURE

摘要

A reinforcement part formed in an intermediate position of either one of left and right front side frames. The reinforcement part has an enhanced strength against a deformation due to a compressive load in front-and-rear directions and a bending load caused when a tip end of the front side frame is pressed from outside in the vehicle width directions, rather than a strength of an area forward of the reinforcement part. A fragile part is formed in an intermediate position of the other front side frame. The vulnerable part has a reduced strength against a deformation due to a bending load when a tip end of the other front side frame is pressed from inside in the vehicle width directions.

1. A vehicle front body structure, comprising:
left and right front side frames in pairs that are formed so as to project forward in a vehicle from a front part of a vehicle cabin, and are disposed so as to be separated from each other in vehicle width directions; a coupling member that couples front end parts of the left and right front side frames; and a power unit disposed in an area that is located between the left and right front side frames and rearward of the coupling member, wherein a reinforcement part is formed in an intermediate position of either one of the left and right front side frames, the reinforcement part having an enhanced strength against a deformation due to a compressive load in front-and-rear directions and a bending load caused when a tip end of the either one of the front side frames is pressed from outside in the vehicle width directions, rather than a strength of an area forward of the reinforcement part, and a fragile part is formed in an intermediate position of the other front side frame, the fragile part having a reduced strength against a deformation due to a bending load when a tip end of the other front side frame is pressed from inside in the vehicle width directions.
