SOLUTION: The swash plate type variable displacement hydraulic pump (1) comprises a cylinder barrel (6) rotated around the axis of rotation, a plurality of axial cylinders (60) formed at equal intervals in the circumferential direction of the cylinder barrel, a piston (61) which is inserted in each axial cylinder so as to be reciprocated, a swash plate (7) which is slidably brought into contact with an end of each piston to provide axial displacement to each piston, and a controller (3) for controlling the angle of the inclination of the swash plate. The controller includes a control cylinder (4) having a control piston (41) connected to the swash plate, and a non-contact linear displacement sensor (5) for directly detecting the displacement of the control piston. The controller performs the feedback of the displacement detected by the linear displacement sensor to control the feed of pressurized oil to the control cylinder.
