装置。[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 inserted into a cylinder hole 11 of the cylinder block 4 to form a cylinder chamber 13. In the variable 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. First port 40 and second port 4 of valve plate 15
A control port 42 is bored in the middle of the rocker cam 18, and high pressure oil is supplied to the control port 42 to apply a tilting force to the rocker cam 18. 1. A rocker cam tilting device for a variable pump/motor, characterized in that the position is shifted toward the outer periphery or inner side of the center circle of the variable pump/motor.
