<p>A small-sized motor of the present invention includes an insulation holder 16 which is integrally molded from a synthetic resin. The insulation holder 16 comprises a cover portion 13 for covering the casing cover 5 from the outside thereof, and a pair of brush holders 12 which project from the cover portion 13 into the interior of the motor, while passing through cut portions formed in the casing cover 5. Each of the brush holder 12 supports a brush arm 17 and an input terminal 11 connected thereto. The brush arm 17 supports a brush 18. Bearings 3 and 6 for the shaft are respectively supported at the center of the bottom portion of the casing 2 and at the center of the casing cover 5. Thus, it becomes possible to realize stable bearing alignment and to provide insulation outside the motor to thereby enable attachment of an electrical element to the motor without use of any additional insulation means. <IMAGE></p> |
