DAMPING DEVICE AND BASE ISOLATION STRUCTURE OF BUILDING
To provide a damping device which has excellent energy absorption performance, which can be used repeatedly, and which can shorten the length in an action direction of an external force.SOLUTION: A damping device 1 is for absorbing energy generated by an external force, and it includes: a movable plate 5 which is formed in a disc-like shape, and in which a peripheral surface 54 becomes an action surface; a first plate 21 and a second plate 22 which are overlapped with the movable plate; a core material part 4 penetrating the overlapped plates, and fitted in restriction holes 211, 221 of the first plate and the second plate; and a spring part 3 which is mounted on an end part of the core material part so that an axial direction becomes an expansion/contraction direction. Then, the plates receive a resilience force from a spring part in a state where irregularity is fitted which is formed so that slide in the axis orthogonal direction occurs with the same magnitude of the force in any direction.SELECTED DRAWING: Figure 1
【課題】エネルギー吸収性能に優れ、かつ繰り返しの使用が可能であるうえに、外力の作用方向の長さを短くすることが可能な制動装置を提供する。【解決手段】外力により生じるエネルギーを吸収させるための制動装置１である。円盤状に形成されて周面５４が作用面となる可動プレート５と、可動プレートに重ねられる第１プレート２１及び第２プレート２２と、重ねられたプレートを貫通するとともに、第１プレート及び第２プレートの拘束穴２１１，２２１に嵌合される芯材部４と、芯材部の端部に軸方向が伸縮方向となるように装着されるバネ部３とを備えている。そして、プレート同士は、軸直交方向の摺動がいずれの方向に対しても同じ力の大きさで起きるように形成された凹凸の嵌め合わせがされた状態でバネ部による復元力を受けている。【選択図】図１
