PURPOSE: A damper grease maintaining structure maintains grease applied between a buffering rod and an operating hole of a lower buffer for a long time to maintain the damping force of a damper fixedly. CONSTITUTION: An etched rough surface(33) maintaining grease is formed on the inner circumference of an operating hole(31) of a lower buffer(3) constituting a damper(D). Frictional heat is generated to abrase the lower buffer(3) as the lower buffer(3) shrinks by a cutout(32) and is compressingly attached to a buffering rod(1) as the buffering rod(1) buffs, the abrasion of the operating hole(31) due to the friction between the lower buffer(3) and the buffering rod(1) is prevented as the etched rough surface(33) maintains grease. |
