PURPOSE: A shock absorber is provided to absorb and alleviate shock during full bump of shock absorber by additionally including a mechanism which fluidic alleviates an impact. CONSTITUTION: A shock absorber(1) comprises an operation tube(10), a piston valve(30), and a shock-absorbing piston(60). The operation tube comprises a first inside diameter unit and a second inside diameter unit which is smaller than the first inside diameter unit. The piston valve has an external diameter corresponding to the inside diameter of the first inside diameter unit so that the piston valve can slide along the inner surface of the first inside diameter unit. The shock-absorbing piston has an external diameter corresponding to the second inside diameter unit so that the shock-absorbing piston can slide along the inner surface of the second inside diameter unit. The shock-absorbing piston includes penetration holes(62) to allow fluid flow while in the second inside diameter unit. The second inside diameter locates in the lower part of the operation tube.
