とする液圧回転機械。[Claims for Utility Model Registration] A rotating cylinder block, a plurality of cylinder chambers each formed in the cylinder block in a direction parallel to its axis, and each cylinder chamber fitted in a reciprocating manner. A piston, a valve plate disposed on the end face of the cylinder block, a pair of suction/exhaust ports respectively opened in the valve plate, and interposed between the valve plate and the cylinder block so as to rotate together with the cylinder block. The cylinder block is equipped with a sub-plate and a communication path opened in the sub-plate and the cylinder block so that both suction/exhaust ports communicate with each cylinder chamber, and a movable member maintains a sealed state in each cylinder chamber. In a hydraulic rotating machine, each movable member is fitted with its position regulated to allow slight movement while maintaining the movable member, and each movable member is provided with a communication hole so as to communicate with the communication path. The movable member has a storage recess that opens on the end face on the sub-plate side around the communication hole, and inside this storage recess, there is a seal member that is slidable on its inner circumferential surface, and this seal member is attached to the sub-plate. A hydraulic rotating machine characterized by housing a biasing member that is pressed into contact with a plate.
