To increase the amount of absorption of impact energy at the time of a side collision and further improve protection performance for an occupant while reducing in weight of an instrument panel reinforcement member and preventing bending deformation at the time of a front collision.SOLUTION: An instrument panel reinforcement member 1 is formed of one plated member continuous from a left end portion 1a to a right end portion 1b and is formed in a pipe shape including a large diameter cylindrical portion 11 located at a driver's seat side, a small diameter cylindrical portion 12 located at a passenger's seat side, and a diameter-reducing cylindrical portion 13 extending with a diameter reduced from the large diameter cylindrical portion 11 to the small diameter cylindrical portion 12. At least one of a recessed portion 14 and a protruded portion is formed at a portion of the diameter-reducing cylindrical portion 13 or the small diameter cylindrical portion 12, which is located adjacent to the diameter-reducing cylindrical portion 13.SELECTED DRAWING: Figure 2

    【課題】インパネ補強メンバの軽量化を図りながら、正面衝突時の曲げ変形を抑制しつつ、側面衝突時の衝撃エネルギーの吸収量を増大させ、ひいては乗員の保護性能を向上させる。【解決手段】インパネ補強メンバ1は、左端部1aから右端部1bまで連続した1枚の板材により形成されるとともに、運転席側に位置する大径筒部11と、助手席側に位置する小径筒部12と、大径筒部11から小径筒部12まで縮径しながら延びる縮径筒部13とを有するパイプ状に形成されている。縮径筒部13または小径筒部12における縮径筒部13寄りの部分には、凹部14と凸部との少なくとも一方が形成されている。【選択図】図2
