To easily manufacture a swash plate capable of tiltably operating a variable displacement hydraulic motor.

The rear surface 32 of the swash plate 30 is formed in a stepped surface with steps 34 and 35. A pair of rear surface portions 32a, 32b, 32b, 32c of the steps 34, 35 adjacent to each other on both sides of the steps 34, 35 are formed in flat surfaces displaced in the axial direction of an output shaft 21 and positioned parallel with each other. The swash plate 30 is supported on a support body 26 so as to be tiltably operated using the corer part 34a of one step 34 as a tilted fulcrum P.
