PROBLEM TO BE SOLVED: To use a large PTC by eliminating a hole, which passes through a motor, and also, securing accurate axial alignment and securing sufficient space for the PTC.;SOLUTION: A case lid assembly is constituted by fitting a resin brush holder and a resin terminal holder integrally to each side of a metal plate for supporting a bearing. The brush holder supports a pair of brush bases, the terminal holder supports a PTC and a pair of conductive members, and the conductive member has a receptacle terminal and a brush base joint. The tip of the brush base penetrates the metal plate to touch the brush base joint of the conductive member and is connected electrically therewith, and the PTC is contained in a PTC inserting portion provided in the brush holder penetrating the metal plate in the thrust direction.;COPYRIGHT: (C)2009,JPO&INPIT
