Viscous shear-type damper

摘要

A viscous shear-type damper is provided with a casing including an upper cover which is horizontally movable and a container portion having a rectangular parallelepiped-shaped accommodating space which is covered by the upper cover; an engaging block provided in the accommodating space in such a manner as to be suspended from a lower surface of the upper cover; a plurality of movable resistance plates which are arranged horizontally one above another in the accommodating space of the container portion while maintaining fixed intervals therebetween and engaging with the engaging block; a plurality of fixed resistance plates which are arranged horizontally and fixed to the casing and which are each interposed between adjacent ones of the movable resistance plates while maintaining a very small gap therewith; a viscous material filled in the accommodating space of the container portion to fill the gap between adjacent ones of the movable resistance plates and the fixed resistance plates; and rectifying sections respectively disposed at end portions of the fixed resistance plates to allow the viscous material to flow.
