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 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. The rear surface 32 of the rocker cam 18 is provided with a plurality of stopper surfaces and arcuate projections 35 at different angles, and an arcuate groove 36 is formed in the bottom wall 1a of the case 1, and the bottom wall 1a is used as a stopper. Rotsuker cam support structure for variable pump motor.
