According to the present invention, a shock absorber comprises: an inner tube and an outer tube wherein a fluid is filled; a piston valve divided into a compression direction and the tensile direction inside the inner tube; and a body valve dividing a storage chamber positioned between the inner tube and the outer tube and the compression chamber. Moreover, the present invention comprises: an auxiliary chamber coupled to an outer circumference of the inner tube and of which an upper portion and the lower portion have a connection passage to communicate with the inside of the inner tube; and a free piston dividing the connection passages inside the auxiliary chamber and vibrated by the fluid accessing through the connection passages when the piston valve is compressed and extended within a gap between the connection passages. |
