Claims (1)

[Claims for Utility Model Registration] (1) The master cylinder is provided in the middle of the hydraulic path from the master cylinder to the operating cylinder of the hydraulically actuated clutch mechanism, and the master cylinder In a vibration isolating device for a hydraulically operated clutch that damps vibrations so as not to transmit vibrations, a pair of pistons are slidably arranged relative to each other within a cylinder formed in the body with a vibration isolating spring in between. The fluid passage to the operating cylinder is secured by the movement of the piston on the master cylinder side against the vibration isolation spring, and when the pedal is returned, the fluid is returned to the master cylinder by the movement of the piston on the operating cylinder side against the vibration isolation spring. A vibration isolating device for a hydraulically operated clutch, characterized in that a valve mechanism is provided to ensure a passage and further close the liquid passage by pressing the piston to both sides by the vibration isolating spring when the pedal is stopped. (2) The valve mechanism includes a liquid passage passing through the center of the piston in the axial direction, an O-ring that closes the liquid passage at the center of the piston when the piston is pressed by the vibration isolation spring, and a piston formed on the liquid inlet and outlet side. A disc-shaped sealing material that is fitted into the small diameter part and closes the liquid passage formed in the large diameter part of the piston by applying hydraulic pressure from the outside to move the piston, and opens the liquid passage by receiving hydraulic pressure from the inside. A vibration isolating device for a hydraulically actuated clutch according to claim 1, characterized in that the vibration isolating device comprises:
