The main member is made of a first material of a plate shape having a predetermined strength, has a pore for mounting a connected body and is formed by being bent into a predetermined shape. The sub member is so formed of a second material having a specific gravity lower than that of the first material as to have a larger thickness than that of the main member, and is jointed around the pore of the main member and formed with an insertion hole for inserting a fastening member to fasten the connected body.</p> |
