Claims

[Scope of utility model registration request]

A third rotating body is attached to one of the driving rotating body and the driven rotating body, which are arranged concentrically and relatively rotatably, and is not relatively rotatable but slidable in the axial direction, and the third rotating body is attached to the other one of the driving rotating body and the driven rotating body, which are arranged concentrically and relatively rotatably. A clutch operation structure in which a retaining portion is fixed to the intermediate rotary body and is engaged and disengaged from the intermediate rotary body by sliding in the axial direction of the rotary body, and a shift fork is engaged with the third rotary body. In this case, a piston portion integrally formed at an end of the fork shaft is hermetically fitted into a case in which the fork shaft to which the shift fork is fixed is fitted and held so as to be slidable in the axial direction thereof. A clutch operation structure comprising: a cylinder section integrally formed with a fluid pressure switching device for sending and discharging oil to and from an oil chamber within the cylinder section;
