CLUTCH DRIVE DEVICE AND VEHICLE

Document Type and Number:

WIPO Patent Application WO/2018/124271

Kind Code:

A1

Abstract:

A clutch drive device that has a self-locking function, wherein a structure is obtained in which the responsiveness of a transfer mechanism can be improved while maintaining the self-locking function. A clutch drive device (14) comprises a friction mechanism (80) that produces a friction force in the opposite direction as a rotation direction of a rotation, said rotation being transferred by a transfer mechanism (60) that transfers the output of a motor to a clutch (13). The friction mechanism (80) has a rotating body (81) that rotates due to a rotation direction force transferred by the transfer (60) mechanism, a friction plate (82) that generates a friction force by coming into contact with the rotating body (81), and a spring (84) that biases the friction plate (82) toward the rotating body (81) so as to bring the friction plate (82) and the rotating body (81) into contact. A rotation transfer part (83) that is positioned so as to be movable in an axial direction with regard to the rotating body (81) and rotates integrally with the rotating body (81) is provided to an intermediate shaft (62) of the transfer mechanism (60).
