PROBLEM TO BE SOLVED: To solve a problem in that moisture may enter the inside of a mold motor from a small space in a boundary between a pressing member and a mold resin.SOLUTION: A motor 1A includes: an annular stator 21A enclosing a center shaft 9A; a rotor 32A disposed at the radial inner side of the stator 21A; an electronic circuit board 22A disposed above the stator 21A; a pressing member 23A configured to contact with an upper surface of the electronic circuit board 22A; and a resin motor casing 24A covering the stator 21A and the electronic circuit board 22A. A hole 240A extending from the pressing member 23A to an upper surface of the motor casing 24A is provided in the motor casing 24A. The pressing member 23A has: a body part 61A having an exposed surface 71A exposed to an area above the motor casing 24A through the hole 240A; and a welding part 62A formed by a thermoplastic resin, having a welding surface 72A welded to the motor case 24A, and welded to the body part 61A.SELECTED DRAWING: Figure 1 |
