Title:
REBOUND RUBBER
Document Type and Number:
WIPO Patent Application WO/2014/061356
Kind Code:
A1
Abstract:
In order to improve the durability of a rebound rubber (21) by preventing damage when the rebound rubber (21) deforms and is caught in the radial clearance between a rebound seat and a cylinder, the present invention is a rebound rubber (21), which is interposed between a spring holder holding one end of a rebound spring and a rebound seat affixed to a piston rod in a rebound spring mechanism of a hydraulic shock-absorbing device, wherein the rubber pressure-receiving surface (24) is arranged radially inward with respect to the radial center line (O) of the rubber volume in a half-cut cross-sectional shape of the rubber, and thus when a compressive load in the axial direction is received, the rubber elastically deforms such that a rubber inner-diameter part (22) flexes and a rubber outer diameter part (23) bulges and protrudes outward in the radial direction.
