Abstract
Double-headed pistons received within cylinder bores in the cylinder block are in engagement with the swash plate via shoes and balls. The pistons each have its intermediate bridge portion formed with at least one lubricating oil-guiding hole extending therethrough from a side surface of the same portion facing the inner peripheral surface of the cylinder bore to the opposite side surface facing the outer fringe of the swash plate. The bridge portion of each piston may also be formed with an axially extending lubricating oil-guiding groove joined at one end to the lubricating oil-guiding hole.
