  • Patent number: 10128721
    Abstract: A motor may include a motor body portion; a connector portion disposed to the motor body portion; and a wiring member electrically connected to the motor body portion. The connector portion has a surface exposed to an outside of the motor body portion. The wiring member includes a plurality of external connection terminals which are connected to the external power supply to protrude from the exposed surface of the connector part. The connector portion is provided with a through hole which extends from the exposed surface toward the accommodating space and connects the outside of the motor body portion and the accommodating space. When viewed in the normal direction of the exposed surface, at least a portion of the through hole is positioned inside an edge of an external connection terminal group which consists of the plurality of external connection terminals.
