Abstract
A motor includes a shaft disposed along a central axis, a rotor fixed to the shaft and capable of rotating around the central axis, a stator outside of the rotor, a first housing including a cylindrical portion and disposed on an outside of the stator, and a second housing disposed on an upper side of the first housing. The second housing includes a top plate and projected portions extending downward and spaced apart. Ribs extending from both end portions of the projected portion in the circumferential direction to an inside in the radial direction as viewed in the axial direction are disposed on a lower surface of the top plate.

A motor comprising:
- a shaft that is disposed along a central axis extending in a vertical direction;
- a rotor that is fixed to the shaft and is capable of rotating around the central axis;
- a stator that is outside of the rotor in a radial direction;
- a first housing that includes a cylindrical portion extending in an axial direction and disposed on an outside of the stator in the radial direction;
- and
- a second housing that is disposed on an upper side of the first housing;
- wherein
- the second housing includes:
- a top plate expanding in a direction orthogonal or substantially orthogonal to the central axis;
- and
- a plurality of projected portions extending downward from an outer edge of the top plate and spaced apart in a circumferential direction;
- a plurality of first ribs, which extend from both end portions of the projected portion in the circumferential direction to an inside in the radial direction as viewed in the axial direction, are disposed on a lower surface of the top plate.
