させることができる。According to the present invention, when a load is applied to the front side member from the front of the vehicle body, the front side member is compressively deformed. In this case, the beads provided on the side surfaces of the front side members and extending in the longitudinal direction of the vehicle body are gradually made wider in the vertical direction of the vehicle body toward the rear, and the number of beads is gradually increased toward the rear. Therefore, the distribution of the total plastic load of the front side member in the longitudinal direction of the vehicle body gradually increases from the front toward the rear. Therefore, the front side member can be sequentially compressed and deformed from the front to the rear in response to a load acting on the front side member from the front of the vehicle body.

(See FIG. 4(A)) gradually widens toward the rear of the vehicle. Therefore, the cross-sectional shape of this portion of the front side member 10 when viewed from the front in the longitudinal direction of the vehicle body is a rectangular shape with two convex portions formed inward in the vehicle width direction, as shown in FIG. 4(A). As shown in FIG. 4(B), the stress distribution at this location is such that the drop in the vertical middle portion of the vertical wall portion 14E is significantly reduced compared to FIG. 3(B).
