To provide a motor in which adhesion of a grease to a circuit board can be inhibited.SOLUTION: A gear housing 31 houses a worm 42 and a worm wheel 43. Rotation of the worm wheel 43 is transmitted to an output shaft 44. An opening portion 33c of the gear housing 31 is closed with an outer cover 61. A circuit board 95 is fixed to the inner side of the outer cover 61. An inner cover 101 is disposed at a position to sandwich the circuit board 95 between the outer cover 61 and the inner cover 101, and overlaps with the entire circuit board 95 in an axis direction D1 of the output shaft 44. Contact brushes 91 and 92 are in sliding contact with a contact plate 51 that rotates integrally with the worm wheel 43, and are switched, in accordance with rotation of the contact plate 51, between a conduction state and a non-conduction state to the contact plate 51. The contact brushes 91 and 92 at least partially overlap with the inner cover 101 in the axis direction D1 between the worm wheel 43 and the inner cover 101.SELECTED DRAWING: Figure 3

    【課題】回路基板にグリスが付着することを抑制できるモータを提供する。【解決手段】ギヤハウジング31は、ウォーム42及びウォームホイール43を収容している。ウォームホイール43の回転は出力軸44に伝達される。ギヤハウジング31の開口部33cはアウタカバー61にて閉塞されている。アウタカバー61の内側には回路基板95が固定されている。インナカバー101は、アウタカバー61との間に回路基板95を挟む位置に位置し出力軸44の軸方向D1に回路基板95の全体と重なる。コンタクトブラシ91,92は、ウォームホイール43と一体回転するコンタクトプレート51に摺接しコンタクトプレート51の回転に伴ってコンタクトプレート51との導通状態と非導通状態とが切り替えられる。コンタクトブラシ91,92は、少なくとも一部がウォームホイール43とインナカバー101との間で軸方向D1にインナカバー101と重なる。【選択図】図3
