PCT No. PCT/JP90/01523 Sec. 371 Date Jul. 12, 1991 Sec. 102(e) Date Jul. 12, 1991 PCT Filed Nov. 21, 1990 PCT Pub. No. WO91/07590 PCT Pub. Date May 30, 1991.The present invention has for its object to provide a swash plate type piston pump/motor which is simple in construction and small in size and which enables a swash plate to be tilted surely. The swash type piston pump/motor is arranged such that a swash plate receiving surface (1) formed in a housing (1) is inclined by a predetermined angle relative to the axis (2) of a rotating shaft (2) so that even when the angle of tilting of the swash plate is increased the distance from the axis of the rotation shaft to the center (12) of a ball (12) which serves as the center of swing of the swash plate can be reduced.
