A motor includes a rotor with one or more magnets, a rotor core holding the one or more magnets, a spacer that contacts the one or more magnets, and a rotor holder. The rotor holder includes a holder lid portion and a holder tubular portion in a tubular shape extending to one side in the axial direction from a radially outer edge of the holder lid portion. The holder lid portion includes a holder first surface that extends radially inward from an inner surface of the holder tubular portion, a holder second surface that extends radially and is radially inward of the holder first surface and on the other side in the axial direction, and a connecting surface connecting the holder first surface and the holder second surface.
