Motor

A motor includes a motor main body including a rotor and a stator, a controller, a housing, and a connector. The housing includes a lower housing that holds the motor main body, and an upper housing that holds the controller and the connector. The upper housing includes a connector holder that protrudes outward in the radial direction from an outer peripheral end of the lower housing. The connector holder includes a connector inserting portion into which the connector is inserted in the axial direction. The connector inserting portion includes a ridge portion, which protrudes outward in the radial direction from a straight line connecting both ends of an inner-peripheral-side wall surface in the circumferential direction, on the inner-peripheral-side wall surface facing, in the radial direction, a surface of the connector facing inward in the radial direction.
