Front-side member structure

Abstract

An object of the invention is to provide a front side member structure that can improve yield strength against a moment generated due to a vehicle collision and the like. A front side member structure according to the invention is provided at a lower portion of a vehicle so as to extend in a longitudinal direction of the vehicle and is used to form a frame of the vehicle. The front side member structure includes an under portion that extends in the longitudinal direction, and a kick portion that is provided at a front portion of the under portion and extends forward and upward. A front contour of the kick portion in the side view of the kick portion is inclined at an angle closer to a right angle than a rear contour of the kick portion in the side view of the kick portion. Accordingly, it is possible to reduce the cross section of a kick member at an upper portion of the kick member where a moment generated due to a vehicle collision and the like is small, and to increase the cross section of the kick member at a lower portion of the kick member where a generated moment is large. Therefore, it is possible to increase yield strength against a moment at a portion where a generated moment is large. As a result, it is possible to achieve the above-mentioned object.
