摘要： A variable displacement hydraulic motor having a swash plate angle adjusting structure. This hydraulic motor has a main case, a rotary shaft rotatably supported in the main case, a plurality of cylinder blocks rotatable with the rotary shaft and including axial plungers, a swash plate member for contacting distal ends of the plungers, pivot shafts for pivotally connecting the swash plate member to the main case such that the swash plate member has a pivoting angle adjustable relative to the main case, and a first and a second hydraulic cylinders arranged at opposite sides of the pivot shafts as seen in a direction parallel to the rotary shaft. The first and second hydraulic cylinders are secured in a region of the main case opposed to the cylinder blocks across the swash plate member. The hydraulic cylinders are operable to contact the swash plate member to adjust the pivoting angle thereof.
