ABSTRACT:
A stepping motor having a cylindrical stator core which is a laminate of plates each formed by blanking of a thin silicon steel plate, stator coils wound on an inner peripheral surface of the stator core, a support member fixed to a part of an outer peripheral surface of the stator core and holding a plurality of terminal plates, and a housing formed by injection molding of a synthetic resin so as to cover the outer peripheral surface of the stator core and an outer surface of the support member. First end portions of the terminal plates are made projected through the housing to the exterior of the housing and are surrounded by a socket wall integral with the housing to form a male connector, while second end portions of the terminal plates are connected with end portions of electric wires which constitute the stator coils, and are embedded in the housing. The distance from an engaging surface of the support member which engages one end face of the stator core up to the first end portions of the terminal plates which constitute the male connector is made coincident with a predetermined value and in this state the support member is held in a predetermined position inside the socket wall.
