VARIABLE DISPLACEMENT SWASH PLATE PUMP MOTOR BEARING HOLDING DEVICE, AND VARIABLE DISPLACEMENT SWASH PLATE PUMP MOTOR

PROBLEM TO BE SOLVED: To provide a variable displacement swash plate pump motor bearing holding device enabling the improvement of the assemblability, and a variable displacement swash plate pump motor. SOLUTION: A swash plate 16 and a link member 41 are engaged with each other at a first projection 46 projecting from the swash plate 16 and a first groove 42 formed in the link member 41. A guide part 23 and the link member 41 are engaged with each other at a second projection 49 projecting from the guide part 23 and a second groove formed in the link member 41. The link member 41 is rotatably supported on a retainer 28 by a rotating shaft 45 projecting from the retainer 28 of a bearing 25 and a shaft insertion part 44 formed in the link member 41. The first projection 46, the second projection 49, and the rotating shaft 45 are arranged parallel to each other in the direction parallel to the axial direction of the rotating shaft of a pump motor, and extend in the direction perpendicular to the axial direction. The position of the shaft insertion part 44 is so set that the center of gravity of the link member 41 is biased to the second groove 43 side of the first groove 42. COPYRIGHT: (C)2008,JPO&INPIT
