Abstract
The present invention provides a method for manufacturing a swash plate type piston pump motor in which: a plurality of pistons are arranged in a circumferential direction on a cylinder block configured to rotate with a rotating shaft; the pistons are guided along a swash plate to reciprocate by rotation of the rotating shaft; a convex portion of the swash plate is slidably supported by a recess of a swash plate support; and a wall formed integrally with the swash plate support is arranged on a normal to at least a part of a supporting surface of the recess, wherein: the supporting surface of the recess is quenched by irradiating the supporting surface with laser light while causing the laser light to scan the supporting surface; and outputs of the laser light are changed in accordance with incidence angles of the laser light with respect to the supporting surface.
