PROBLEM TO BE SOLVED: To provide waterproofing property for a motor itself by mounting a doughnut-type printed circuit board near a cylindrical housing pressingly fitted to the opening of a cylindrical bottomed stainless case so as to form a bearing part, a case press-fit part, and the cable taking-out part of the printed circuit board into a waterproof structure. SOLUTION: A cylindrical stator 2 formed so that a coil may be wound and epoxy resin may be electrophoretic coated is pressingly fitted to a cylindrical bottomed stainless motor exterior case 1. A rotor 3 turnably supported by a ball bearing 4 pressingly fitted to the bottom of the motor exterior case 1 and a sealed bearing 5 pressingly fitted into a housing 9 is inserted and mounted in a stator A web washer 6 is disposed between the bearing 4 and the motor exterior case 1, and the rotor 3 is biased the housing 9 so as to prevent rattle in a motor shaft direction, thereby rotating the motor smoothly. The sealed bearing 5 is formed into the sealed structure of lubricating oil by means of a seal member of synthetic rubber between inner and outer laces, and the cable taking-out part is inserted into the waterproof housing 13. |
