ABSTRACT:
A swashplate type variable displacement hydraulic device is so constructed that a plurality of plungers are slidably received in a plurality of cylinder bores arranged annularly around an axis of rotation, a back surface of a swashplate of which a fore surface is engaged by outer ends of the plungers is supported by a swashplate holder via bearing means, and a stationary swashplate anchor supports the swashplate holder to turn about a trunnion axis which intersects the axis of rotation at right angles. Opposing surfaces of the swashplate holder and swashplate anchor are formed as spherical surfaces of which a center is located at a position where the axis of rotation intersects the trunnion axis, the swashplate holder has a pair of trunnion shafts projected from opposite ends of the swashplate holder while extending along the trunnion axis, and the trunnion anchor is formed at opposite ends thereof with recesses with which the trunnion shafts are rotatably engaged.
