Damper and automobile seat having the damper

摘要

A damper ( 1 ) has silicone-based unvulcanized rubber ( 4 ) interposed between a housing ( 2 ) and a shaft ( 3 ) which are disposed in such a manner as to be relatively rotatable about an axis (A) in (R) directions with respect to each other, and rotational energy between the housing ( 2 ) and the shaft ( 3 ) is absorbed through the deformation of the silicone-based unvulcanized rubber ( 4 ).
