Claims

[Scope of utility model registration request]

A hydraulic cylinder communicating with the clutch master cylinder, a hydraulic piston inserted into the hydraulic cylinder and interlocking with the release fork of the clutch, a power piston interlocking with the hydraulic piston via a push rod, and a power piston interlocking with the hydraulic piston via a push rod. Therefore, the power cylinder is divided into a front chamber and a rear chamber, and the rear chamber is provided with a return spring that urges the power piston toward the front chamber when the clutch is engaged.One end of the power cylinder communicates with the front chamber and the other end is connected to the air an air pipe that communicates with a supply source and supplies air to the front chamber of the power cylinder to operate the release fork of the clutch when the clutch is disengaged; and an air pipe that is provided in the middle of this air pipe to supply air to the front chamber of the power cylinder when the clutch is engaged. 1. A clutch booster comprising an air exhaust port for discharging air, the clutch booster comprising a variable valve for restricting the amount of air discharged when the transmission is in a predetermined gear position.
