予圧構造。[Claims for Utility Model Registration] A cylinder block 4 is rotatably supported together with a shaft 6 in a case 1, and a piston 12 is fitted into a cylinder hole 11 of the cylinder block 4 to form a cylinder chamber 13. In the swash plate type pump/motor, the chamber 13 is sequentially communicated with the high pressure port and the low pressure port of the valve plate 15, and the piston shoe 16 connected to the piston 12 is slidably pressed by the shoe retainer 17 along the front surface of the rocker cam 18. Retainer guide 4 to cylinder block 4
2 is integrally provided, and the center part of a preload spring 43 is swingably supported on the spherical guide surface 42a of this retainer guide 42. A preload structure for a swash plate type pump/motor, characterized in that the center of the spool retainer 17 is supported at the center of the swash plate 43.
