扉に固定される係り具と、建具に固定される緩衝本体と、緩衝本体に回動可能に配備され係り具に係脱する操作アームとからなり、緩衝本体はケース体内に配備される固定ラックと、固定ラックにかみ合うピニオンを備え、操作アームの回動に応じて回動すると共に、両側に連繋配備される圧縮バネのバネスライダー及びダンパーのダンパスライダーを、それぞれ押す方向へ直動するカムギヤと、上記ピニオンが固定ラックから離れると圧縮バネの反発力を受け止めるストッパ手段とからなることを特徴とする緩衝装置。





It consists of a hook that is fixed to the door, a cushioning body that is fixed to the fitting, and an operation arm that is rotatably deployed to the cushioning body and engages and disengages from the hooking tool. And a cam gear that has a pinion that meshes with the fixed rack, rotates according to the rotation of the operation arm, and directly moves the spring slider of the compression spring and the damper rider of the damper, which are connected and deployed on both sides, in the pushing direction. A shock absorber comprising a stopper means for receiving the repulsive force of the compression spring when the pinion is separated from the fixed rack.
