SMALL-SIZED MOTOR

摘要

A small-sized motor (1) which can ensure a high reliability against grease leaking from an output-side bearing and oil flowing in from an associated device, and which has a wall (14) provided on a bracket (10) and having a constant gap along the periphery of an output shaft (3) between a commutator (7) and a bearing (6), whereby grease leaking from the bearing (6) on the output side and oil flowing in from an associated device can be prevented from sticking to the commutator (7) and a brush (5) to thereby prevent abnormal abrasion of the brush (5) and the performance deterioration of the small-sized motor (1).
