PURPOSE: To simplify and reduce the dimension of a supporting structure on the swash plate holder of a swash plate, securing the favourable lubrication, by interposing a radial bearing member and a thrust bearing member between the swash plate and the swash plate holder and forming a recessed part for storing the lubricating oil on one surface of both the bearing members.
CONSTITUTION: A number of cylinder holes 17 and 28 are arranged in annular form on the cylinders 16 and 27 which are supported in turnable manner on a casing 44. Plungers 18 and 29 are fitted in slidable manner in the cylinder holes 17 and 28, and the edge parts are engaged with the front surfaces of the swash plates 19 and 30 which are supported on the swash plate holders 22 and 33. In this case, the cylindrical radial bearings 211-214 are interposed between the outer peripheries of the swash plates 19 and 30 and the swash plate holders 22 and 33. Further, flat plate shaped thrust bearings 201-204 are interposed between the edge surfaces on the opposite sides of the cylinders 16 and 27 of the swash plates 19 and 30 and the swash plate holders 22 and 33. Further, at lesst on one surface of both the bearing members 20 and 21, a plurality of recessed parts for storing the lubricating oil are formed.
