<p>PROBLEM TO BE SOLVED: To solve the problem that the conventional variable speed transmission which is constructed so that an charged hydraulic pressure is induced so sliding surface of bearing and movable swash plate through the oil gallery which needs many holes and plugs to close those holes, and this has increased in the assembling man-hour and the number of composing parts for axial piston pump motor. SOLUTION: By shaping the bearing holder 25 is shaped in one body with housing 1 and projecting the bearing fixing pin 25a from bearing holder 25 together, the pressured oil from charged oil gallery 6a in the oil gallery plate 6 is induced into penetration hole through 15 which penetrates abovementioned pin 25a through oil galley 11, 12, 13, 14, etc., which are formed in the housing and is supplied to the sliding surface of the bearing 24 with cradle swash plate 23 from above through hole 15.</p> |
