PURPOSE: To make assembly and wiring efficient by providing a number of connection pins and connector pins on an inner side of a connector cover formed together with a motor case in such a way that the connection pins and connector pins are projectingly provided on a printed board, and by legs are erected for attaching this cover thus assembled to a stator on the motor case.

CONSTITUTION: A motor case 2 of an electric motor and a connector cover 6 are cylindrically formed together by resin material. A number of connection pins 5 and connector pins 7 are planted on an inner side of the cover. The connection pins 5 are connected to a printed board 4 that extends to the rear side of the connector cover 6, and the connector pins 7 are inserted into predetermined holes. A number of legs 9, used for attaching the cover thus assembled to a stator, are provided on an inner side of the motor case 2, and the cover is connected to the stator. Thus, wiring and assembly are efficiently carried out.
