とを特徴とする油圧回路。[Claim for Utility Model Registration] The first hydraulic pipe line and the second hydraulic pipe line are set such that depending on the rotation direction of the hydraulic pump, the hydraulic pipe line on one side is set as the discharge pipe of the hydraulic pump. and the hydraulic line on the other side is set as the suction line of the hydraulic pump, and there is a hydraulic pressure between the first hydraulic line and the second hydraulic line, and the relief valve and the reservoir. In a configuration in which a switching valve is provided, the hydraulic switching valve switches the high pressure side hydraulic pipe by the hydraulic pressure of the high pressure side of the first hydraulic pipe or the second hydraulic pipe. A hydraulic circuit characterized in that a passage is connected to the relief valve, and a side thereof that becomes a low-pressure side hydraulic line is connected to the reservoir.
