ダ。 The rod cover side end of the rod side chamber in the cylinder body in which the main piston fixedly attached to the piston rod slides back and forth is composed of a small diameter piston part facing the main piston and a large diameter piston part facing the rod cover. A cylindrical booster piston forming an annular axial through hole is disposed between the two rods, and a check valve is configured in the through hole in cooperation with the booster piston to allow flow only from the rod cover side to the main piston side. A hydraulic cylinder characterized in that a sleeve-shaped valve body is inserted and the end face of the valve body on the rod cover side can be slightly protruded from a large diameter piston portion of a booster piston.
