Abstract

A hydraulic pump that allows a drive source to be started with a small torque includes a cylinder block having a plurality of cylinder bores and disposed so as to be rotatable. Pistons are each movably retained in an associated one of the cylinder bores. A swash plate controls the amount of movement of the pistons in accordance with the size of the tilt angle. A first pressing unit is configured for pressing the swash plate in such a direction as to reduce the tilt angle of the swash plate, and a second pressing unit is configured for pressing the swash plate to increase the tilt angle of the swash plate by the pressure supplied from the outside.
