A slant plate type hydraulic device comprising:
- a casing;
- a cylinder block rotatably mounted in said casing and having a plurality of axial bores;
- a slant plate arranged to face said cylinder block and to rotate relative to the same;
- a multiplicity of plungers arranged in an annular array around said axis to freely slide in said bored in the axial direction of said cylinder block;
- a slant plate holder mounted in said casing and supporting said slant plate;
- and
- a shoe attached to the leading end of each of said plungers and held in sliding contact with said slant plate, the improvement comprising said slant plate having a lubricant chamber enclosing the sliding contact portions of said slant plate and said shoes to confine lubricating oil therein, a press plate having a plurality of through holes being rotatably mounted on said slant plate holder, said shoes and said leading ends of said plungers extending through said through holes, and an axially extending cylindrical partition being provided on an inner circumference of said slant plate holder, said press plate and said partition together with said slant plate holder defining said lubricant chamber.
