圧緩衝器のピストン構造。 The cylinder has a cylindrical body, a cylinder that is inserted into the body and forms an oil reservoir between the body, and a piston rod that extends outward at one end of the body to receive an impact load, and A piston is movably housed in a cylinder, and the piston is moved relative to the cylinder by external force to cause the oil in the cylinder to flow out into the oil reservoir, and the oil passage resistance generated at this time is buffered. In the hydraulic shock absorber configured to obtain the effect, the piston and the piston rod are formed separately, and an oil drain oval hole is bored in the radial direction of the front end surface of the piston with a hole diameter that prevents the ball check valve from coming out. In addition, a valve seat hole and an orifice communicating with the oval hole and into which the ball check valve is loosely fitted are bored in the axial direction of the piston rod, and a radial orifice communicating with the orifice. A piston structure for a hydraulic shock absorber, characterized in that the ball check valve is loosely fitted into a seat hole, and a piston and a piston rod are integrally connected.
