<p>PURPOSE:To reduce the numbers of assembling steps and components by forming a bent portion at a metal stay for grounding a negative brush, and securing a brush holder between the bent portion and a stationary unit. CONSTITUTION:A metal stay 7 is welded fixedly to the inner periphery of the end of a yoke 1. The stay 7 is formed in an L shape, and a bent portion 7a is formed at a part. The pigtail 6b of a negative brush 6 is welded to the stay 7 to be grounded. A resin brush holder stay 5 is interposed between the bent portion 7a and a pole core 1a of a stationary unit, and the brush 6 is contained in the holder. Thus, a conductive member for the ground can be also used as a member for fixing the holder to reduce the numbers of assembling steps and components thereof.</p> |
