PROBLEM TO BE SOLVED: To provide a motor with a reduction gear which achieves downsizing.SOLUTION: A motor with a reduction gear includes: a housing 20; a stator 30; a rotor 40 having a motor shaft 41; and a speed reduction mechanism 50. The speed reduction mechanism 50 has: a ring gear 51; a sun gear 52; planetary gears 53; and a planetary carrier 54. The motor with the reduction gear includes: a first bearing 60 which rotatably supports the motor shaft 41; a second bearing 70 formed by a needle bearing which supports the motor shaft 41 and the planetary carrier 54 so that the motor shaft 41 and the planetary carrier 54 rotate relative to each other; and a third bearing 80 which rotatably supports the planetary carrier 54 and is disposed so that at least part thereof overlaps with an oil seal 55 in an axial direction.SELECTED DRAWING: Figure 1 |
