造。[Scope of claims for utility model registration] (1) Cylinder block 4 and shaft 6 in case 1
A piston 12 is fitted into the cylinder hole 11 of the cylinder block 4 to form a cylinder chamber 13, and the cylinder chamber 13 is successively communicated with the high pressure port and the low pressure port of the valve plate 15. In a variable pump motor in which a piston shoe 16 connected to a piston 12 is slidably pressed by a shoe retainer 17 along the front surface of a rocker cam 18, the rear surface 32 of the rocker cam 18 has a plurality of stopper surfaces with different angles and an arcuate protrusion 35. 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. Arc-shaped bottom surface 36 of groove 36
1. A rocker cam support structure for a variable pump/motor, characterized in that a is gradually inclined downward toward the outer circumferential side of a case 1. (2) The arcuate surface 35a of the arcuate protrusion 35 has a cross-sectional shape perpendicular to the arc, and the arc of the arcuate groove 36 has the bottom surface 36a a cross-sectional shape perpendicular to the arc. A rocker cam support structure for a variable pump/motor according to claim 1, wherein the rocker cam support structure has a shape.
