Abstract: A motor includes a casing including a wall portion and a bottom portion on an outside of the wall portion in an axial direction. The bottom portion includes a bearing holding portion in a center region of the bottom portion, and a base portion between the wall portion and the bearing holding portion. The base portion includes a plate-shaped portion and a protrusion portion in the plate-shaped portion. The protrusion portion includes a first protrusion portion protruding from an outer surface on an outside of the plate-shaped portion in the axial direction toward an outside of the casing in the axial direction, and a second protrusion portion protruding from an inner surface of the plate-shaped portion in the axial direction toward an inside of the casing. The first protrusion portion and the second protrusion portion oppose each other.
