PROBLEM TO BE SOLVED: To provide a vehicular bumper structure capable of enhancing the absorption efficiency of an impact load, and simplifying the structure. SOLUTION: In this structure, a reaction force to absorb an impact load during the collision is separately generated from the force to project a piston 8, and the absorption performance of the impact load F is not affected by the projection of the piston 8, and the absorption efficiency of the impact load F can be enhanced. Further, no mechanism of keeping the piston 8 in a retracted state is required, and the structure can be simplified. When a vehicle is collided, a cylinder 7 is retracted by the impact load F, and moved while a pin 13 is moved expanding a narrow impact load absorption groove 15. Therefore, a predetermined reaction force can be generated, and the impact load F can be reliably absorbed. COPYRIGHT: (C)2006,JPO&NCIPI
