A swash plate plunger type pump-motor comprises a casing, a rotatable cylinder block formed with chambers, a plurality of plungers axially slideably received in the chambers, rotatable swash plate rotatably supported through a bearing within the casing, a plunger retainer adapted to prevent the plungers from disengaging from the swash plate, and a rotational shaft on which the cylinder block is fixedly mounted. The plunger retainer and the swash plate are connected with each other in such a manner that the front faces of the plunger head portions contact the swash plate and that the rear faces of the plunger head portions contact the plunger retainer. The rotational axis of the swash plate is inclined at a predetermined angle with respect to the rotational axis of the rotational shaft.
