摘要

Provided is an electric motor in which it is possible to accurately leading-out terminal sections of a magnet wire that constitutes a stator coil in a prescribed leading-out direction as lead wires. A wire cover formed from a hard insulating resin is press-fitted into a wire leading-out hole provided in an end member that closes one end of a motor housing, and lead wires are led out to an exterior through through-holes provided in the wire cover. Crush ribs are provided to side surfaces of a head part of the wire cover, and, due to crushing of the crush ribs and press-fitting of the wire cover into the wire leading-out hole, the wire cover is prevented from inclining within the wire leading-out hole and a leading-out direction of the lead wires is prevented from deviating from the prescribed leading-out direction.
