PROBLEM TO BE SOLVED: To provide an instrument panel beam having high torsional stiffness, high bending stiffness, and a small mass, and to provide one pair of brackets and an instrument panel beam joint.SOLUTION: An instrument panel beam 110 is disposed in a vehicle width direction and includes: a large diameter hollow pipe 200 having a hollow cylindrical diameter shape; and a small diameter hollow pipe 300 which is coupled to the large diameter hollow pipe 200 in an axial direction and has a hollow cylindrical diameter shape having a diameter smaller than the large diameter hollow pipe 200. The small diameter hollow pipe 300 has two flat plate parts extending in a longitudinal direction and two curve parts curved in a circumferential direction. The flat plate parts and the curve parts are alternately disposed in the circumferential direction.SELECTED DRAWING: Figure 1
【課題】高いねじり剛性および高い曲げ剛性を有し、質量の小さいインストルメントパネルビーム、一組のブラケットおよびインストルメントパネルビーム接合体を提供する。【解決手段】インストルメントパネルビーム110は、自動車の幅方向に配置されるインストルメントパネルビーム110であって、中空の円筒径状を有する大径中空管200と、大径中空管200に軸方向に結合され、大径中空管200より小さい径の中空の円筒径状を有する小径中空管300と、を備える。小径中空管300は、長手方向に延在する2つの平板部と周方向に湾曲した2つの湾曲部とを有し、平板部と湾曲部が周方向に交互に配置される。【選択図】図1
