| Abstract | One object is to provide a hydraulic pump that allows a drive source to be started with a small torque. The hydraulic pump (10) includes: a cylinder block (30) having a plurality of cylinder bores (32) and disposed so as to be rotatable; pistons (38) each retained in associated one of the cylinder bores (32) so as to be movable; a swash plate (40) for controlling the amount of movement of the pistons (38) in accordance with the size of the tilt angle; a first pressing unit (50) for pressing the swash plate (40) in such a direction as to reduce the tilt angle of the swash plate (40); and a second pressing unit (60) for pressing the swash plate (40) in such a direction as to increase the tilt angle of the swash plate (40) by the pressure supplied from the outside. |
