Pistons inserted into multiple cylinders drilled in the axial direction around the axis of a rotating cylinder block are reciprocated via a swash plate, and hydraulic oil is sucked from each cylinder port via a fixed valve plate. In a swash plate type axial piston pump configured to discharge, a return port is provided between the low pressure port and the high pressure port of the fixed valve plate, and when both of the return ports are communicated with each other, each of the cylinder ports is Provide a notch,
A swash plate type axial piston pump, characterized in that only the cutout portions meet symmetrically with each of the return ports.
