A hydraulic pump that can perform stable operation while suppressing an increase in size is provided. The hydraulic pump (10) has a cylinder (30) that rotates about a rotation axis (A) and is formed with a plurality of cylinder bores (32); a piston (38) that is slidably held in each cylinder bore (32); a sloping plate (40) for rotating the cylinder (30) about the rotation axis (A) to slide each piston (38) in each cylinder bore (32), wherein the sloping plate (40) being configured to be a deflection angle of which can be changed; a first urging member (50) biasing the sloping plate (40) opposite the deflection angle of the sloping plate; and a second urging member (60) biasing the sloping plate (40) toward the deflection angle of the sloping plate, wherein the second urging member (60) hasa biasing lever (61) for biasing the sloping plate (40), at least one of the flow control signal pressure and the horsepower switching signal pressure acts on an end face (61b) of the urging lever (61) on the side opposite t
