description The invention discloses an oil pressure drive system and a gate valve. The oil pressure drive system is an oil pressure drive system that can expand and contract so as to press an object in a chamberin a vacuum atmosphere. The oil pressure drive system has a vacuum actuator and an oil pressure driving unit. The oil pressure driving unit includes an oil pressure generating unit, a driving unit fordriving the oil pressure generating unit, and a power source for supplying power to the driving unit. A telescopic rod can be driven by working oil pressure supplied from the oil pressure driving unit to the fixed section. The driving unit is provided with a reversal response portion, and when the telescopic rod moves in a direction away from the object by the force of an oil pressure urging member, the reversal response portion responds to the reverse state of the motor.
