PROBLEM TO BE SOLVED: To prevent side members from being bent by the increase of an interval between bumper stay mounting parts when the bent part of a bumper reinforcement is extended at the time of collision against a barrier without lowering the impact absorbing capacity of a bumper stay. SOLUTION: This aluminum alloy extruded material bumper stay 11 fixed between the bumper reinforcement having right and left end part tilted to a body rear side and the side members comprises a front flange 13, a rear flange 14, an intermediate flange 15, a pair of front webs 16 and 17 connecting the front flange to the intermediate flanges, and a pair of inner and outer rear webs 18 and 19 connecting the intermediate flanges to the rear flange. The inner front web 16 is tilted outward in the lateral direction of a vehicle. The rigidities of both forward and backward hollow structure parts are set so that, at the time of collision, a forward hollow structure part 11a starts to bend in the lateral outward direction of a vehicle body before a rearward hollow structure part 11b.
