Abstract: A tubular piston mounted at one end of a rod accommodated inside a cylinder and partitioning the space inside the cylinder includes first groove and second groove recessed from an outer circumferential surface thereof and aligned side by side along a centerline direction of the cylinder, and a communication passage communicating an end face on the side of an opening in the centerline direction of the cylinder with one of the two grooves (second groove) formed on the side of the opening. A rubber-made annular sealing member having an outer circumferential surface contacting an inner circumferential surface of the cylinder is fitted in the second groove. A resin-made restrictor ring that is a C-shaped member fitted in the first groove has an outer circumferential surface positioned closer to the inner circumferential surface of the cylinder than the outer circumferential surface of the piston.
