Abstract
A clutch driving device having a self-lock function includes a friction mechanism that generates a friction force in a direction opposite to a rotation direction of rotation transferred by a transfer mechanism that transfers an output of a motor to a clutch. The friction mechanism includes a rotation body that rotates by the force in the rotation direction transferred by the transfer mechanism, a friction plate that generates a friction force by contact with the rotation body, and a spring that biases the friction plate toward the rotation body such that the rotation body and the friction plate are brought into contact with each other. An intermediate shaft of the transfer mechanism includes a rotation transfer portion that rotates together with the rotation body and is movable in the axial direction relative to the rotation body.
