PURPOSE: A wobble plate type piston pump is provided to prevent a mounting part of a shoe from applying compression load to a plate spring by closely contacting in a peripheral direction, and reduce ununiform spring force applied to the shoe since an outer periphery of the plate spring is extended to the whole periphery. CONSTITUTION: A wobble plate type piston pump includes a mounting part(32) rotatably mounted with front end parts of a plurality of pistons inserted in a cylinder block connected to an output shaft, a shoe(31) for sliding around the output shaft on a sliding surface of a wobble plate(30), and an annular plate spring(42) positioned between plate spring supporting parts mounted around the output shaft, wherein the plate spring is penetratingly inserted with the mounting part of the shoe in insertion penetrating holes formed with a same interval in a peripheral direction and supported by the plate spring supporting part at an inner periphery part for elastically applying force to the shoe toward the wobble plate, wherein the plate spring and the shoe is mounted with a coupling element(40) for preventing relative peripheral displacement of the plate spring and the shoe under the state that the inner periphery of the insertion penetrating part of the plate spring and the mounting part of the shoe are separated in the peripheral direction. |
