ABSTRACT:
A damper for use on a motor vehicle has a fluid cylinder, a piston axially slidable in the cylinder, and a piston rod secured to the piston. A seal incorporated in the damper includes an annular contacting portion held in contact with the outer peripheral surface of the piston rod and a resilient connecting portion having one end joined to the contacting portion and the other end secured to the inner peripheral surface of the cylinder. Due to the resiliency of the resilient connecting portion, the contacting portion is movable with the piston rod to a certain extent when the piston rod is moved with respect to the cylinder in a higher-frequency, smaller-amplitude range.
