WIPO Patent Application WO/2018/079578

A1

[Problem] To make it possible to reduce costs while providing a motor with: a resin sealing member covering a stator; and a cover member that supports a rotating shaft and that is fixed to the resin sealing member. [Solution] A motor provided with: a resin sealing member 12 that is made from a resin and that covers a stator; and a cover member 13 that is fixed to the resin sealing member 12. A plurality of protrusions 12h protruding radially outward are formed on the resin sealing member 12. A part of the cover member 13 on a Z2 direction side thereof is configured as a cylindrical cover section 13a covering the resin sealing member 12 from the outer circumferential side. The cover section 13a has formed therein notch sections 13g-13j, engagement grooves 13p-13s that extend toward one side in the circumferential direction from the ends of the notch sections 13g-13j on a Z1 direction side and with which the protrusions 12h engage, and a stopper 13k restricting movement of the cover member 13 toward the other side in the circumferential direction. The widths of the notch sections 13g-13j are wider than the widths of the protrusions 12h in the circumferential direction.
