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.

說(shuō)明書(shū)

FIGS. 1 to 5 show the entire configuration of the electric motor 1 according to the present embodiment. In these drawings, reference symbol 2 indicates a motor housing, and reference symbol 3 indicates a motor body (see FIGS. 4 and 5) accommodated within the motor housing.

The motor housing 2 is configured from a cylindrical part 200 formed in a cylindrical shape, and a first end member 201 and a second end member 202 that respectively close one axial end and another axial end of the cylindrical part 200. In the example shown in the drawings, the first end member 201 is formed integrally with the cylindrical part 200, and the second end member 202 is formed separately from the cylindrical part 200. These parts of the motor housing 2 are formed from aluminum or another metal material.

The second end member 202 is formed substantially in a cup shape, and a cylindrical part 202a (see FIG. 4) formed on one axial-end side of the second end member 202 is closely fitted to an inner periphery of another axial end 200a of the cylindrical part 200.
