ABSTRACT:
Disclosed is a cylinder protective apparatus for preventing strange noise in which an impact damper is fixed to an inner side of a cylinder cover to prevent collision between the cylinder cover and a cylinder or a cylinder guide from occurring, which may be caused by vibration generated when a heavy construction equipment such as an excavator works. Since the cylinder protective apparatus is provided with the impact damper, strange noise due to a gap generated between the cylinder cover and the cylinder or the cylinder guide can be prevented from occurring.
