MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a motor capable of securing the strength of the whole output shaft, reducing a vibration noise, and suppressing a sliding loss of the output shaft.SOLUTION: A motor 1 comprises: a motor main body part 10; an output shaft S; a deceleration gear part 20; a case main body 310; and an end plate 320 formed with a bearing part 321 that rotatably supports the output shaft S. The output shaft S comprises: a resin cylindrical part ST that configures a bearing surface sliding with the bearing part 321 of the end plate 320; a resin gear part SC engaged with an output side gear 211 of the deceleration gear part 20; and a metal shaft part SZ formed integrally with the cylindrical part ST and the gear part SC. The shaft part SZ has: a first portion P1 overlapped with the cylindrical part ST in a radial direction; and a second portion P2 that protrudes from the cylindrical part ST to the other side in an axial direction. A boundary part J between the second portion P2 and the cylindrical part ST is provided radially inside an outer peripheral edge of the cylindrical part ST.SELECTED DRAWING: Figure 2
