ダンパー。 A cylinder whose inner periphery is coated with highly viscous grease and whose one end is closed, a rod inserted into the cylinder so as to be able to move forward and backward, and an elastic rod attached to the tip of the rod that makes sliding contact under load with the inner peripheral surface of the cylinder. A piston-type damper comprising a load member, in which the inner periphery of the closed end of the cylinder is formed by concentrically expanding the diameter to an arbitrary width in the longitudinal direction, and the load member is an umbrella whose peripheral edge is oriented in the opening direction of the cylinder. 1. A piston-type damper comprising a piston, characterized in that the forward and backward movement of the rod is under no load only when the umbrella-shaped piston is on the enlarged diameter inner periphery.
