Abstract
Disclosed is a friction damper that has a unique load-displacement hysteresis characteristic such that, when the frictional coefficient between members that generate friction is smaller than the slope of an inclined surface, the friction damper is always returned to the original position thereof in a case where an external force is removed or remains at a level that does not exceed a threshold value. The V-groove friction damper includes: a V-groove member including a concave V-shaped groove; a V-shaped frictional contact member including a V-shaped frictional contact portion; a guide member configured to guide a left/right movement of the V-groove member; and an elastic compression unit installed on the guide member, and configured to elastically compress the V-shaped frictional contact member toward the V-groove member.
