PROBLEM TO BE SOLVED: To provide an axial piston pump bearing supporting device capable of reducing an influence on a bearing even when high pressure is applied to a discharge port. ! SOLUTION: An axial piston pump is equipped with a casing; a shaft supported by the casing through a bearing; a cylinder block which has a plurality of cylinder bores extending in parallel with an axis of the shaft and opening on a front end side and a rear end side, and is supported by the shaft; pistons slidably fitted in the cylinder bores; a swash plate with which front ends of the pistons can contact, and which is provided so as to incline to the shaft; a suction port and a discharge port which can communicate with the rear ends of the cylinder bores, and are provided in the casing. Between the suction port or the discharge port and the bearing provided on the casing, a deformation absorbing portion for absorbing the deformation of the suction port or the discharge port is provided. !
