<P>PROBLEM TO BE SOLVED: To surely lubricate a space between the sliding protrusion of a supporting body and the sliding recess of a swash plate, without bringing problems such as the swash plate moving relative to a casing, and the like. <P>SOLUTION: A ball retainer 50 has a sliding protrusion 52 formed at the tip end part of a shaft 51, with a through oil path 53 being formed in the location from the outer surface of the shaft 51 to the outer peripheral surface of the sliding protrusion 52, while fittingly engaged with the mounting hole 11b of the casing 10 via the shaft 51, to be further slidingly fit with the sliding recess 32 of the swash plate 30 via the sliding protrusion 52 in a state of covering the opening of the through oil path 53. The casing 10 has a communication path 56 formed from an accommodation space 21A that accommodates a body side bearing 21 to the mounting hole 11b, while a lubrication grooves 54 is formed between the sliding protrusion 52 of the ball retainer 50 and the sliding recess 32 of the swash plate 30, so that the opening of the through oil path 53 is in a state of communication at all times with the area outside the sliding area between the sliding protrusion 52 and the sliding recess 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
