To ensure necessary fixing strength in consideration of a characteristic of electromagnetic molding when a member is attached to an instrument panel reinforcement of a vehicle by utilizing electromagnetic molding.SOLUTION: An instrument panel reinforcement fixing structure includes a pipe member 42 extending in a width direction of a vehicle, an instrument panel reinforcement fixed to the vehicle, and a member to be fixed 20 having a through hole 26 and being joined to the periphery of the pipe member 42. End surfaces 28 and 30 of the through hole 26 are shaped in such a manner that at least part of each of the end surfaces does not become orthogonal to the direction of the through hole. Outside the end surfaces 28 and 30 of the through hole 26, the pipe member 42 has a larger diameter than an internal wall 24 of the through hole 26, and clamps the member to be fixed 20. Accordingly, the member to be fixed 20 is caulked and secured by the pipe member 42.SELECTED DRAWING: Figure 3
【課題】電磁成形を利用して、車両のインパネリインフォースメントに部材を取り付ける場合には、電磁成形の特性を勘案した上で、必要となる固定強度を確保する必要がある。【解決手段】インパネリインフォースメント固定構造は、車両の幅方向に延びるパイプ部材42を備え、前記車両に固定されたインパネリインフォースメントと、パイプ部材42の外周面に接合した貫通孔26を備えた被固定部材20と、を備え、貫通孔26の両端面28、30は、ともにその少なくとも一部が、貫通孔方向と直交しない形状で形成されており、貫通孔26の両端面28、30の外側では、パイプ部材42は貫通孔26の内壁24よりも拡径されて、被固定部材20を挟み込んでおり、これにより、被固定部材20がパイプ部材42によってかしめ固定されている。【選択図】図3
