PROBLEM TO BE SOLVED: To provide a motor which has a worm gear and a planetary gear and enables reduction of its dimension in an output shaft axial line direction. SOLUTION: This motor 1 has a yoke 4, a rotary shaft 7 on which worm 11 is formed in a part protruding from the yoke 4, rotary elements 27 and 28 which have a worm wheel part 27a geared with the worm 11 and a sun gear 28 fixed to a position shifted in a direction of one axis of the worm wheel part 27a, a planetary gear 30 geared with the sun gear 28, a carrier 29 which is provided at a position shifted in a direction of one axis of the planetary gear 30 and supports the planetary gear 30, an output shaft 31 fixed to the carrier 29, and housings 20 and 21 by which an internal gear 26 geared with the planetary gear 30 is fixed and the output shaft 31 is supported rotatably. The base end of the output shaft 31 is fixed to the carrier 29 so as to have the output shaft 31 extended in a direction of the other axis, and the output shaft 31 is supported at two positions on the other axial direction side of the worm wheel 27a.
