PURPOSE:To eliminate the positional relationship between a cylindrical bracket and a stator even if an external force is applied to the bracket by forming grooves at the stator and the bracket, and inserting a ring into the grooves to secure both. CONSTITUTION:A ring 12 is inserted into the groove 11a of a cylindrical bracket 11. Then, the ring 12 is retained by the outer surface of the bracket 11 so that the entire periphery of the ring 12 may not be projected from the outer periphery of the bracket 11, and the bracket 11 is press-fitted to a stator 10. When press-fitted to the position where the groove 11a of the bracket 11 coincides with the groove 10a of the stator 10, the three positions of the retained ring 12 are introduced into the grooves 10 of the stator 10 by its own elastic force. According to the construction, since the stator 10 and the bracket 11 are secured by the ring 12, even if an external force is applied to the bracket 11, the positional relationship between both does not alter. |
