ABSTRACT:
A piston-cylinder type air damper includes a cylinder having an open end and a closed end, a piston having a head slidable along and in contact with the inner wall of the cylinder and a rod extending axially from the head and projecting outwardly from the open end of the cylinder, and a cap fitted upon the open end of the cylinder and permitting the rod to centrally penetrate therethrough. The cap is molded from a soft material into a C-shaped cylinder having a slit and two outwardly projecting claws formed upon the outer periphery thereof within the vicinity of the opposite ends thereof which define the slit therebetween. The cylinder has a hole formed within a side wall portion thereof at the open end thereof for engaging the two claws of the cap therein.
