MOTOR AND PRODUCTION METHOD OF MOTOR

摘要

A motor, wherein a motor case (5) and a reduction gear case (7) are integrally provided, a hole portion (8) through which the output shaft (3a) of a rotor (3) extends from the motor case side toward the reduction gear side is provided at a location shared by these cases, and lubricating oil (9) is filled inside the reduction gear case. A production method of the motor comprising the steps of allowing resin (11) to flow into the motor case for hardening, and tightly depositing the resin on an armature coil and the inner surface of the motor case. The motor case (5) comprises a first case member (510), a second case member (520) and a third case member (530) for covering a control unit (4), the first case member and the second case member, and the first case member and the third case member being respectively assembled.
