Claims

[Scope of utility model registration request]

A casing having an inlet/outlet port, an input/output rotating shaft supported by the casing, a torque plate rotatably provided on the rotating shaft, and an inclined axis that intersects with the rotation center of the torque plate. a cylinder block that is rotatably provided in the cylinder block and has a plurality of cylinder holes parallel to the tilted axis and opened toward the torque plate; a plurality of pistons pivotally supported on the torque plate; and a connection port provided in the casing to be attached to the end surface of the cylinder block on the opposite side of the torque plate, for connecting the inflow/outflow port and each cylinder hole. A piston pump or a motor, comprising: a valve surface having a rotary shaft or a synchronizing mechanism for synchronizing the rotations of the cylinder block and the torque plate; a fitting recess having a polygonal cross section and having a planar inner surface, which is fixed to one of the rotating shaft or the cylinder block with its axis aligned with the other; and a fitting convex portion having a polygonal cross section and each outer surface of which has a convex arc surface shape, and the fitting convex portion and the fitting concave portion are arranged at an inclination angle of the inclined axis. 1.
