Abstract:
A clutch comprising:a driving rotor coupled to a driving source, wherein the driving rotor has a driving engagement body; a driven rotor directly engaged with the driving rotor such that the driven rotor is driven by the driving rotor, wherein the driven rotor has a driven engagement body that is opposite to the driving engagement body and is directly pressed by the driving engagement body in the circumferential direction of the driven rotor, and wherein rotation of the driving rotor is transmitted from the driving engagement body to the driven rotor through the driven engagement body; a housing for accommodating the driving rotor and the driven rotor; and a lock member located between the driven rotor and the housing, wherein, when the driven rotor itself is rotated, the lock member is held between the driven rotor and the housing to block rotation of the driven rotor relative to the housing, and wherein, when the driving source rotates the driving rotor, the lock member is released from the held state to allow the driving rotor to rotate the driven rotor relative to the housing and is circulated about an axial center of the driving rotor without being held between the driving rotor and the driven rotor.
