摘要： [PROBLEMS] To enhance the wear resistance and seizure resistance of the sliding surfaces of a swash plate and a swash plate support base while improving productivity. [MEANS FOR SOLVING THE PROBLEMS] In the swash plate type piston pump motor (1), pistons (10) are circumferentially disposed in a cylinder block (9) rotating together with a rotary shaft (5). The tip end (10a) of each piston (10) is guided by the sliding surface (26a) of the swash plate (12) whereby the piston (10) is reciprocatingly moved. The projected surface (32) of the swash plate (12) is slidably supported on the recessed surface (22) of the swash plate support base (4) whereby the swash plate can be tilted relative to the rotating axis (L). The recessed surfaces (21, 22) of the swash plate support base (4) have hardened parts (21a, 22a) partially hardened by laser beam.
