Abstract: A clutch device includes a first rotor, a second rotor, a third rotor, at least one bolt, at least one anti-slip member, and a cam mechanism. The first rotor has a first cam surface and a first fitting hole extending in an axial direction. The second rotor has a second cam surface. The third rotor has a second fitting hole. The second cam surface presses the first cam surface in a circumferential direction. The second fitting hole faces the first fitting hole and extends in the axial direction. The third rotor is fixed to the first rotor. The bolt connects the first rotor and the third rotor. The anti-slip member fits into the first and second fitting holes. The cam mechanism includes the first cam surface and the second cam surface, and moves the second rotor in the axial direction when relative rotation occurs between the first rotor and the second rotor.
