Abstract
A hydraulic damper includes a tubular main body, a piston rod slidably extending through one end of the tubular main body, an annular seat member secured to an outer peripheral wall of the tubular main body, a biasing device such as a coil spring or an air spring acting between the seat member and the tip end of the piston rod for biasing the piston rod in the extending direction, and a supporting member constituting a part of the biasing device and having a tubular portion which is slidingly fitted on the seat member. A resilient retaining member is provided on the seat member for engaging with a retaining recess formed in the inner circumferential surface of the tubular portion of the supporting member, thereby preventing the supporting member from escaping from the seat member.
