Zusammenfassung: | A motor includes a rotor including a shaft extending along a center axis in a lengthwise direction, the rotor being rotatable about the center axis, a stator opposite the rotor with a clearance between the stator and the rotor in a radial direction, and a housing accommodating the rotor and the stator. The housing includes a tubular portion extending along the center axis, and a bottom portion closing a lower opening of the tubular portion. The tubular portion includes, on its inner peripheral surface, a fitting portion fitted to the stator, and a tapered portion with a diameter gradually decreasing downward and located below the fitting portion. The tubular portion includes, in its outer peripheral surface, a recessed portion with an axial position overlapping the tapered portion and extending in a circumferential direction. |
