<p>According to the present invention, a shock absorber comprises: an inner tube and an outer tube wherein a fluid is filled; a piston valve dividing a compression chamber and a tension chamber inside the inner tube, and performing a compression routine and the tension routine by an external force; and a body valve dividing a storage chamber between the inner tube and the outer tube and the compression chamber. The shock absorber comprises: a free piston dividing a gas chamber and the oil chamber inside the storage chamber, and moving in both directions when the piston valve performs the compression routine and the tension routine; and a buffer unit supporting the free piston downwards inside the gas chamber, enabling a reaction force to be applied to the free piston to absorb an impact when the piston valve performs compression and tension routines.</p> |
