In a swash plate type hydraulic unit for use as a swash plate type hydraulic pump and a hydraulic motor, a plurality of block plates,to,being divided at split planes extending orthogonal to a cylinder block axis X are soldered to one another to form a cylinder block,. Inlet holes,and,for supporting plungers,and,slidably therein are formed in an inlet-side one of the block plates,,,;,,,located close to plunger swash plates,and,, while in remaining inner-side ones of the block plates,to,;,to,are formed inner holes,and,of a diameter larger than that of the inlet holes,and,, the inner holes,and,each defining an oil chamber to which the outer peripheral surface of the associated plunger,,,faces. With this arrangement, a cylinder block structure superior in mass-productivity is provided.
