Abstract:
The present invention provides a motor, which comprises a resin sealing member covering a stator, and in which a connector to which a conducting wire is connected has an improved waterproof property, with said connector being protected. A motor 2 of a pump apparatus 1 comprises: a resin sealing member 13 covering a stator 11; and a cover member 14 covering the resin sealing member 13 from an output side L1. The resin sealing member 13 comprises a connector sealing part 66 projecting toward an outer circumferential side of a stator core 51 to cover a connector 54. The connector sealing part 66 is shaped to protrude toward an opposite output side L2 beyond a sealing member bottom section 65 covering the stator core 51 and a coil 53. A connection opening 30a, into and from which an external connector is attached and removed, is positioned to protrude further from the connector sealing part 66 toward the opposite output side L2.
