Abstract: PURPOSE:To improve reliability and producibility of a shock absorber by reducing assembling measurement error of valve elements of two check valves which are serially arranged in the shock absorber. CONSTITUTION:Two check valves 30, 40 are serially arranged in a passage 22 for communicating a cylinder upper chamber 6 with a lower chamber 8, at its opening on the cylinder lower chamber side. In one aspect, valve support seats 30b, 40b and valve seats 30c, 40c of the check valves are formed as one member such as a piston main body 20. In another aspect, the valve support seat and valve seat of one check valve is formed on the piston main body, while the valve support seat and valve seat of the other check valve is formed on another member such as an intermediate member to be fixed to the piston main body.
