PURPOSE: An air exhaust system is provided to reduce maintenance and repair time by quickly discharging air from an oil pipe connected from the oil storage tank to the clutch booster with the simple structure, and to keep the working area clean by preventing leak of oil. CONSTITUTION: An air exhaust system discharges air from an oil pipe(20) connected from an oil storage tank(10) to a clutch booster(30) operating a clutch plate, and comprises a cylinder(40) connected to the pipe extended from the clutch booster and filled with oil and an operating rod(50) sending oil to the oil storage tank. While sending oil from the oil pipe to the oil storage tank by actuating the operating rod, air is exhausted to the oil storage tank. The cylinder is combined with a cylinder cover(41) to restrict leak of oil in pressing the operating rod.
