PROBLEM TO BE SOLVED: To provide a coupling device and a coupling device installation structure in which a damper does not cause attenuation force in a small earthquake.SOLUTION: A coupling device 1 couples, to each other, a damper 2 which is arranged between an upper structure body 3 and the ground 4, and a fixing part 5 which is fixed to the upper structure body 3 side or the ground 4 side. The coupling device 1 includes a main body 20 which is fixed to the fixing part 5, a movable body 10 which is fixed to the damper 2 and is movable relatively against the main body 20, a locking part 30 which is movable with the movable body 10 in a forward direction F and a backward direction B, a first contacting part 26 which is provided at the main body 20 and contacts the locking part 30 in the forward direction F, to restrict movement of the movable body 10 in the forward direction F, and a second contacting part 28 which is provided at the main body 20 and contacts the locking part 30 in the backward direction B, to restrict movement of the movable body 10 in the backward direction B.SELECTED DRAWING: Figure 2 【課題】 小さな地震ではダンパが減衰力を発生しない連結装置およびその連結装置の設置構造を提供する。【解決手段】 連結装置１は、上部構造体３と地盤４との間に配置されるダンパ２と、上部構造体３側または地盤４側に固定される固定部５とを連結する。連結装置１は、固定部５に固定される本体２０と、ダンパ２に固定され、本体２０に対し相対的に移動可能な可動体１０と、可動体１０と共に前進方向Ｆおよび後退方向Ｂに移動可能な係止部３０と、本体２０に設けられ、前進方向Ｆで係止部３０に接触して可動体１０の前進方向Ｆの移動を制限する第１当接部２６と、本体２０に設けられ、後退方向Ｂで係止部３０に接触して可動体１０の後退方向Ｂの移動を制限する第２当接部２８と、を含む。【選択図】 図２
