Abstract:
Provided is a shock absorber capable of smoothly changing a damping force in a low speed range of piston speed and of opening a main valve with a smaller differential pressure. An auxiliary valve ( 111 ) is provided on an upstream side of a main valve ( 27 ) in series with the main valve ( 27 ). Thus, the damping force in the low speed range of the piston speed can be smoothly changed. Further, the main valve ( 27 ) has a simply-supported structure in which an inner peripheral side thereof is prevented from being clamped and is supported in a cantilever state. Thus, the main valve ( 27 ) can be opened with a smaller differential pressure.

Claim (Index 5):
A shock absorber according to  claim 1 , further comprising a leakage prevention valve, which is configured to prevent the hydraulic fluid from leaking to the pilot chamber side through between the inner peripheral side of the main valve and the first retainer, the leakage prevention valve having an outer peripheral side that is to be brought into abutment on the outer seat portion side of the main valve, and having an inner peripheral side clamped from both surface sides of the leakage prevention valve.
