バ。[Claims for Utility Model Registration] (1) Hydraulic oil from upstream passes through the annular gap formed between the upper surface of the outer peripheral end of the upper leaf valve and the lower surface of the seat opposite to the upper surface of the outer peripheral end of the upper leaf valve. By passing through the lower leaf valve, it is possible to generate a damping force in a low speed range of the piston speed, and by bending the outer peripheral end of the lower leaf valve, it is possible to generate a damping force in a medium to high speed range of the piston speed. A shock absorber characterized in that the inner peripheral ends of the upper leaf valve and the lower leaf valve are laminated and fixed. (2) The shock absorber according to claim 1, wherein the annular gap is formed in advance regardless of whether or not hydraulic oil passes from the upstream side. (3) Utility model registration claim No. 1 in which the annular gap is formed when the outer peripheral end of the upper leaf valve is bent.
Shock absorber as described in section. (4) The shock absorber according to claim 1, wherein the seat portion is formed on the lower surface of the piston body in the cylinder piston portion. (5) The shock absorber according to claim 1, wherein the seat portion is formed on the lower surface of the valve case in the in-cylinder base valve portion.
