Abstract
A cylindrical cylinder chamber formed by a casing and having inlet and outlet ports for pressure liquid at its both axial ends is installed in a liquid passage communicating a liquid chamber of the master cylinder device with a liquid chamber of the slave cylinder device. A cylindrical friction member divided circumferentially into plural pieces contacting with a peripheral wall of the cylinder chamber, a moving body carrying the friction member, plural first urging members fitted to the moving body for pressing the friction member onto the peripheral wall of the cylinder chamber, and a second urging member for urging the moving body in its axial direction in order to locate the moving body at a prescribed axial position of the cylinder chamber, are installed in the cylinder chamber. An orifice is formed on the moving body or the friction member in the axial direction.
