Claims

[Scope of utility model registration request]

A booster body, a power piston that slides within the booster body, a spool that slides within the power piston, a link member that is rotatably installed in conjunction with a clutch pedal, and rotation of the link member. an operating rod that moves in a direction to slide the spool, and a boost chamber formed on the rear end side of the power piston, and when the spool moves forward due to the movement of the operating rod, the boost chamber is In a hydraulic booster that increases hydraulic pressure and operates the power piston using the hydraulic pressure, the link member is locked in a predetermined assembly position between the link member and the booster body to prevent rotation of the link member. A hydraulic booster characterized by having a fixing member that is detachable.
