A motor according to a preferred embodiment of the present disclosure includes a rotor arranged to be capable of rotating about a central axis, a stator located radially outside of the rotor, a housing arranged to house the rotor and the stator, and a plurality of bolts arranged to fasten the stator to the housing. The housing includes a tubular portion arranged radially outside of the stator to surround the stator; a plurality of stator support portions each of which is arranged to project radially inward from an inner circumferential surface of the tubular portion, and includes a seating surface arranged to face a first axial side; and screw holes each of which is arranged to open in the seating surface of a separate one of the stator support portions. The stator includes a plurality of through holes each of which is arranged to extend along an axial direction. The bolts are passed through the through holes of the stator and screwed into the screw holes of the stator support portions. The housing includes a rib arranged to project radially outward from an outer circumferential surface of the tubular portion on the first axial side of the seating surfaces of the stator support portions.
