PROBLEM TO BE SOLVED: To provide a bearing restricting device for a swash plate hydraulic pump or motor. SOLUTION: In the swash plate hydraulic pump or motor, a convex arc surface on the back surface of a swash plate is supported on a concave arc surface of a swash plate support part via a bearing so as to enable the arc surface to swing in the circumferential direction following the arc path. A restricting pin is included for restricting movement of the bearing. The assembly structure prevents the restricting pin from coming out of the swash plate and the swash plate support part. One end of the restricting pin is supported rotatably on a side surface of the swash plate. An intermediate portion of the restricting pin is loosely fitted to and engaged with an engagement hole formed on a holder of the bearing. Finally, the other end of the restricting pin is inserted to a support rod supported rotatably around its axis on the swash plate support part to permit movement of the restricting pin in a pin axial direction.
