摘要： This invention provides a piston in which the moving piston unit can be prevented from rotating with respect the base piston unit, while suppressing the increase of the sliding resistance the piston has with respect to the cylinder. The circumferential wall of the moving piston unit has a pair of skirt parts opposing each other across a piston boss and a pair of side-wall parts coupling the skirt parts and each having an outer circumferential surface concaved toward the central axis X1 of the piston. The side-wall parts have a penetration part each, which penetrates the side-wall part and extends in the directions the moving piston unit reciprocates with respect to the base piston unit. The base piston unit has rotation preventing projections that project perpendicular to the central axis of the piston and are inserted into the penetration parts.
