Claims

[Claims for Utility Model Registration] (1) A rotating member that is rotatable around the clutch axis, and a stationary member that fits into the inner peripheral surface of the rotating member and is movable only in the axial direction. A rolling element cam mechanism comprising an axially moving member and a release bearing coupled to the axially moving member, and between the rotating member and the axially moving member, converting rotation of the rotating member into axial movement of the axially moving member. The cam mechanism has a plurality of rolling elements spaced apart in the circumferential direction,
A clutch release bearing drive mechanism is characterized in that a rotating member and a clutch pedal are interlocked and connected by a wire. (2) The clutch release bearing drive mechanism according to claim 1, wherein a drive motor is used together with the wire as a drive source for the rotating member.
