<P>PROBLEM TO BE SOLVED: To provide a hydraulic motor reduced in size and weight in the hydraulic motor in which a speed reducer member is mounted to a housing member and a brake piston slidably fitted into the housing member. <P>SOLUTION: A hydraulic motor 10 includes a housing 13 comprising a case 11 and a plate 12. A cylinder block 18, together with a shaft 19, is axially supported in the housing 13 via bearings 20, 21. A cylinder hole 22 of the cylinder block 18, into which a piston 23 is slidably inserted and fitted, forms a cylinder chamber 24, and the piston 23 is freely slidable along a swash plate 26 via a shoe 25. A circular cross section recess 39 is formed at a part in an axial center direction side, in a contact surface 12a of the plate 12 with a back surface of the swash plate 26. <P>COPYRIGHT: (C)2013,JPO&INPIT |
