PURPOSE: A valve structure of shock absorber is provided to appropriately control a damping force rising according to a property of a spring constant by using a disc valve and an elastic member such as a spring to control the damping force in a compression stroke. CONSTITUTION: A valve structure of shock absorber comprises a piston valve(120). A piston valve comprises a piston body(124) and a valve member. One or more paths where an operating fluid passes through while a shock absorber operates are formed in the piston body. The valve unit is installed in the upper or lower part of the piston valve, thereby generating the damping force with respect to the pressure of the operating fluid passed through the path formed in the piston body. The valve member comprises a pilot case(133) where a back pressure chamber is formed. The damping force property of the operating fluid is improved by elastic members(137,147).
