Front side members (11, 12) are formed with outward bent portions (11A,
12A) at the front sides. Bumper reinforcement (13) is formed with
rear slant portions (13A) at the both ends. The front ends of the outward
bent portions (11A, 12A) are connected with the rear slant portions
(13A). Interference members (40) are formed on the rear side of the
proximal portions of the outward bent portions (11A, 12A). The interference
members (40) interfere with power unit (P) to restrict a deformation of
the front side member at a collision. Side members (31) of a sub frame (30)
are stronger than the outward bent portions (11A, 12A) and the front
end positions (K1) of the outward bent portions (11A, 12A)
are arranged on the inside in the vehicle width direction and on the rear side
in the vehicle fore and aft direction of the front end positions (K2) of
the outward bent portions (11A, 12A).
