手段を設けたことを特徴とする油圧取出装置。[Scope of Claim for Utility Model Registration] A hydraulic pressure supply path 5 that communicates between the hydraulic pump 3 and the actuator 4 and a hydraulic pressure return path 7 that communicates between the actuator 4 and the oil tank 6 are formed in the hydraulic pressure extraction block 2. In the hydraulic pressure extraction device in which a coupler on the actuator 4 side can be connected to the hydraulic pressure supply path 5 and the hydraulic pressure return path 7, a bypass passage 22 is formed in the hydraulic pressure extraction block 2 to short-circuit the hydraulic pressure supply path 5 and the hydraulic pressure return path 7. A hydraulic pressure extraction device characterized in that an on-off valve 23 is provided in the bypass passage 22, and interlocking means is provided between the on-off valve 23 and the coupler to open the on-off valve in conjunction with the detachment operation of the coupler.
