To provide a cylinder block structure excellent in mass productivity in a swash plate type hydraulic device to be used as a swash plate type hydraulic pump and a hydraulic motor.
A plurality of block plates 41 to 45 divided by a dividing surface perpendicularly intersected with the axial line of a cylinder block, are mutually brazed so as to be formed into a cylinder block 4, inlet holes 25i and 39i pivotally supporting plungers 27 and 41 in such a way as to freely slide, are formed in the inlet side block plates 41, 42; 44, 45 at places close to a plunger swash plate, and back holes 25o and 39o lager in diameter than the inlet holes 25i and 39i, are formed in remaining back side block plates 43 to 45; 41 to 43, which partition oil chambers to which the outer rcicumferential surfaces of the plungers 27 and 41 are faced.
