ABSTRACT:
To reduce dispersion in an engagement stroke amount caused by error in manufacturing parts and to reduce the stroke amount in a stationary cylinder type clutch device, the clutch device includes a hub, a drum, friction coupling elements connecting thereto such that rotational power can be transmitted, a pressing member and a reaction force member arranged at opposite ends of the clutch device in the axial direction, and a hydraulic servo for engaging and disengaging the friction coupling elements where the hydraulic servo is installed to a fixed member, a servo force is transmitted to the friction coupling elements via the pressing member and the reaction force caused by the engagement is supported by the fixed member via the reaction force member. A return spring, for retracting a piston of the hydraulic servo, is installed between the pressing member and the reaction force member whereby the piston is retracted via the pressing member and the amount of retraction is restricted to a predetermined value by a regulating element.
