A piston ring for sealing the cylinder wall is provided on the piston body. Piston rings, and extending about the one axis (line) and a ring body having an inner surface and an outer surface. The inner surface, the presence of a pair of ridges (ridges) extending in a radially inward direction, and the groove is present outside surface. The spring of the elastic material is substantially surrounds the ring body in a circumferential direction, it is accommodated in a groove on the outer surface. The spring, biases the ring body in a radially inward direction to the ridge seal about the piston body. In addition, the ring body and has an angle at least one of the endosperm port extending about the radially inward facing side of one axis of the spring from the inner surface to transport the fluid outside the space between the ridge to a position on the outer surface.
