Claims

[Scope of utility model registration request]

A master cylinder having a piston rod that is reciprocated by a clutch pedal, and a working fluid generated by the reciprocating movement of the piston rod of the master cylinder,
In a clutch device including a release cylinder having a piston rod serving as an output end for switching a clutch mechanism, the master cylinder side passage and the release cylinder side passage are provided in the working fluid passage connecting the master cylinder and the release cylinder. Conclusion A hollow chamber with an enlarged inner diameter is formed with a stepped wall that expands radially outward from the master cylinder side passage entrance and exit, and the master cylinder side passage is connected to the master cylinder side passage while the outer peripheral portion is in sliding contact with the inner wall of the hollow chamber. A movable valve body that reciprocates along the fluid flow from the inlet/outlet to the release cylinder side passage inlet/outlet is provided, and the valve body is formed with a main passage hole whose diameter is reduced to match the master cylinder side passage inlet/outlet, and the above-mentioned step An auxiliary passage opening facing the step wall is provided, and the auxiliary passage is opened and closed by moving the valve body in the fluid flow direction and separating the valve body from the step wall. A clutch control device characterized by:
