FRICTION DAMPER
PROBLEM TO BE SOLVED: To restrict a reduction in efficiency of a friction damper caused by a bending moment acted against the friction damper.SOLUTION: This invention relates to a friction damper comprising a first press contacting plate integrally arranged with one of a pair of members and bridged between the pair of members; a second press contacting plate integrally arranged with the other of a pair of members; and a fastening member for press contacting plate thickness direction crossing at a right angle with an opposing surfaces of the first press contacting plate and the second press contacting plate. A bending moment acts on the friction damper, and a moment of inertia of area of a section where a location of the first press contacting plate positioned between one member and the fastening member in a prescribed direction is cut along a width direction and the plate thickness direction is larger than a moment of inertia of area of a section where a location in the locations at the first press contacting plate overlapped on the fastening member in a prescribed direction enclosed by its opposing surface against the second press contacting plate, the opposite surface against the opposing surface, its extended surface and a pair of side surfaces in a width direction is cut along the width direction and the plate thickness direction.
【課題】摩擦ダンパーに作用する曲げモーメントによる摩擦ダンパーの効率低下を抑制する。【解決手段】一対の部材のうちの一方の部材に一体に設けられ、一対の部材間に掛け渡される第１圧接板と、一対の部材のうちの他方の部材に一体に設けられる第２圧接板と、第１圧接板と前記第２圧接板の対向面に直交する板厚方向に第１圧接板と第２圧接板とを圧接させる締結部材と、を有し、当該摩擦ダンパーには曲げモーメントが作用し、所定方向において一方の部材と締結部材の間に位置する第１圧接板の部位を、幅方向と板厚方向とに沿って切った断面の断面二次モーメントが、所定方向において締結部材と重複する第１圧接板の部位のうち、第２圧接板との対向面と、当該対向面の反対側の面及びその延長面と、幅方向における一対の側面とで囲われた部位を、幅方向と板厚方向とに沿って切った断面の断面二次モーメントよりも大きい摩擦ダンパー。【選択図】図５
