IPC: H02K5/08
Filed: 1982-06-08
Abstract: PURPOSE:To obtain an accurate bearing structure by providing a through hole at the side face of a bearing cylinder which is externally engaged with th bearing of a rotational shaft, inserting resin through the hole at the molding time and supporting the bearing with the immersed resin, thereby reducing the number of assembling steps. CONSTITUTION:A bearing cylinder 12 which is externally engaged with the bearing 6 of a rotational shaft 4 is formed of a material different from a molding resin, a through hole 13 is formed at the side face, a stepped part 14 is formed with resin immersed into the cylinder 12 through the hole 13 at the molding time, thereby supporting the bearing 6. In this case, the length L of the cylinder 12 may be shorter than the size of the size L0 of a mold, and it is not necessary to accurately finish the difference L of both sizes. It is not necessary to mix low contraction resin in the resin. Since the cylinder 12 is insert molded through the hole 13, processing for fixing in a rotating direction and preventing the cylinder from being removed become unnecessary.
