A dust cover prevents the contact with the piston rod or cylinder, and accordingly prevent to the noise as well as the permanent deformation of product and damage. A dust cover is mounted on the piston rod(54) upper end of the shock absorber(50), is installed in order to surround the partial upper of the cylinder(52) and piston rod, and prevents piston rod blocks to be exposed to the foreign body. In the process where the piston rod compresses, it can be contacted with the top cap of cylinder, accordingly the dust cover(70) is bent with predetermined amount, the extent in which the wide portion of the central part is bent is absorbed, and is transformed into the form which the times is more full and the other side nearly maintains the strait type to one side.
