PURPOSE: A shock absorber for a vehicle is provided to prevent oil of an inner tube from leaking out of a cylinder by discharging pressure of the inner tube to a reservoir with a pressure reducing device and to prevent operational noise in bump and rebound. CONSTITUTION: A shock absorber for a vehicle has a pressure reducing device(70) for an inner tube(22) on an upper portion of the inner tube. A connecting hole(22a) is formed to connect the inner tube with a reservoir(21a). The pressure reducing device is installed movably to the connecting hole to connect the inner tube and the reservoir selectively. Therein, pressure reducing device reduces pressure of the inner tube by discharging rebound pressure of the inner tube to the reservoir in rebound of a piston rod. Therefore, oil filled in the inner tube is not leaked and operational noise is reduced in bump and rebound of the shock absorber.
