Abstract:
A motor may include a rotor including a rotating shaft that protrudes to a first side in an axial direction; a stator disposed on an outer peripheral side of the rotor; a resin sealing member that covers the stator; and a cover member that is disposed on the first side of the resin sealing member and supports the rotating shaft. The resin sealing member may include a resin sealing member side position regulating surface that makes contact in the axial direction with a cover member side position regulating surface provided on the cover member, and a resin sealing member side securing surface that faces, in the axial direction and with a gap, a cover member side securing surface provided on the cover member. At least a portion of the resin sealing member side securing surface is secured to the cover member side securing surface via an adhesive agent layer.
