PROBLEM TO BE SOLVED: To provide a motor in which a coupling strength between a rotary shaft and a rotator is improved, and the stability of a rotor is ensured during rotation.SOLUTION: In the motor including a stator and a rotor rotated supported by the stator, the rotor includes the rotary shaft 30 rotatably supported by the stator, the rotator 10 rotated integrally with the rotary shaft 30, and a hub 20 which includes a ring-shaped body interposed between the rotary shaft 30 and the rotator 10, and has a protrusion 22 in the body in a way that it extends the outer peripheral surface of the body coupled with the rotator 10. The protrusion 22 may protrude toward the stator, the rotator 10 can include a support step to support the protrusion 22, and the hub 20 can further include a wedge 24 coupled with the rotary shaft 30. |
