PROBLEM TO BE SOLVED: To provide a rotor which achieves downsizing and simplification of a structure which inhibits winding wires from moving in an outer periphery direction.SOLUTION: An inner rotor 101 provided at an inner rotary shaft 2 including a shaft part 2b and a diameter expansion part 2a includes: an inner core 11; winding wires 12; stopper members 13; connection members 14; and fixing members 15. The inner core 11 includes: a cylindrical body part 11a enclosing an outer periphery of the diameter expansion part 2a; and tooth parts 11b which protrude from an outer peripheral surface 11a1 of the body part 11a and are disposed spaced away from each other along a circumferential direction. The stopper members 13 protrude from end surfaces 11b2, 11b3 of each tooth part 11b and are disposed at the radial outer side relative to the winding wire 12 wound around the teeth part 11b. Each ring shaped connection member 14 connects the stopper members 13, which are provided at the end surfaces 11b2 or 11b3 positioned at the same side in an axial direction and located adjacent to each other in the circumferential direction. The fixing members 15 connect each connection member 14 to the diameter expansion part 2a and fix the connection member 14 thereto. |
