PROBLEM TO BE SOLVED: To provide a motor which allows thickness reduction in the axial direction, while maintaining a swing angle of a top member.SOLUTION: A joint part 13 comprises: a pin member 21 which is arranged on an output shaft 12 so as to be perpendicular to a rotation axis L1 of the output shaft 12; a top member 22 which is swingably supported by the pin member 21 and coaxially rotates with the output shaft 12; and an input cam 23 which forms an annular shape surrounding the outer periphery of the top member 22 and integrally rotates with the top member 22. The top member 22 has an insertion part X into which the pin member 21 is inserted. An edge face of the top member 22 on a housing 14 side is provided with a first displacement surface 31 which is spaced apart from the housing 14 farther than the insertion part X when the top member 22 is in its equilibrium state. |
