Abstract

A clutch hydraulic mechanism wherein the positional relationship between two cylinders is not varied, and a compact structure can be achieved. A see-saw member for transmitting motive power is provided between a second release cylinder and a first master cylinder and the first master cylinder and the second release cylinder are formed in the same cylinder block. This eliminates the need for adjusting the positions of the first master cylinder and the second release cylinder. In addition, it is possible to dispose the first master cylinder and the second release cylinder close to each other.
