摘要:PURPOSE:To improve the accuracy of positioning a stator of a pulse motor for a watch by integrally forming a rotor inserting portion formed on a base plate and one or more projections formed with the stator inserting portion, thereby simplifying the procedure of assembling the motor. CONSTITUTION:A hole 2a for inserting a rotor 3 and a hole 2b for preventing a stator 2 from rotating are formed at the stator 2. A hole 1b for inserting the shaft of the rotor 3, a projection 1a for restricting the position of the stator 2, and a projection 1c for preventing the stator 2 from rotating are integrally formed by a plastic injection molding at a base plate 1 to be associated with the stator 2. The projections 1a, 1c are respectively engaged with the holes 2a, 2b. In this manner, the assembling work is accurately performed.
