Patent ID: 6968930

Claim:
A damper, comprising: a cylinder having an opening portion, a piston rod inserted into the cylinder through the opening portion, and formed of a plate member with a plate surface, said plate member including a front end, a base end at a side opposite to the front end and having a flange projecting outwardly from the plate surface, and an inclining part as a frictional engaging member provided on the plate surface thereof along a longitudinal direction thereof extending from a portion near the front end to the base end, said inclining part having a height gradually increasing toward the base end, a cover fitted to the opening portion of the cylinder and having a through-hole for receiving the piston rod therethrough, and resistance means disposed at the opening portion of the cylinder, said resistance means being formed of a spring member with two spring portions at the opening and sandwiching the inclining part to contact the frictional engaging member and deform elastically to thereby gradually increase frictional resistance to the piston rod as the piston rod is withdrawn from the cylinder, said resistance means including a pressure piece provided at a side of the through-hole for contacting the inclining part, said spring member being attached to the cover for urging the pressure piece toward the inclining part.
