Abstract

Provided is a hydraulic rotary machine configured so as to reduce the sliding resistance of a reciprocating piston and so as to suppress a reduction in volumetric efficiency corresponding to the amount of leakage of hydraulic oil. A piston pump (1) is provided with a rotating shaft (11), a cylinder block (12), a piston head (13), a piston rod (14), a retainer (15), a swash plate (16), and a tilt regulation mechanism (17). When the tilt regulation mechanism (17) rocks the swash plate (16), the amount of discharge from the piston pump (1) is variably changed. The retainer (15) which rotates with both the piston head (13) and the piston rod (14) is supported by a retainer bush (11A) provided to the rotating shaft (11). The retainer sphere section (15A) of the retainer (15) and the retainer bush sphere section (11B) of the retainer bush (11A) have spherical shapes having the same curvature. During the regulation of tilt, the retainer (15) rocks while the retainer bush sphere section (11B) is in sliding contact with the retainer bush (11A).
