To provide a shock absorbing device which is excellent in accuracy, stability and durability of operation and which is miniaturized by rotating a cam gear according to the rotating direction of an operation arm and concurrently operating a compression spring and a damper by linear movement.SOLUTION: A buffer device is made up of: an engagement member 8 fixed to a door A; a buffer body C fixed to a fixture B; and an operation arm 7 that is provided in a rotatable manner on the buffer body C to engage and disengage the engagement member 8. The buffer body C is made up of: a fixed rack installed inside a case body 1; a cam gear that is provided with a pinion meshing with the fixed rack and that rotates according to a rotation of the operation arm 7, and that moves directly in the direction of pushing a spring slider of a compression spring and a damper slider of a damper which are connected to both sides, respectively; and stopper means for receiving repulsive force of the compression spring when the pinion is separated from the fixed rack.SELECTED DRAWING: Figure 1
【課題】操作アームの回動方向に応じてカムギヤが回動すると共に直動して圧縮バネ及びダンパーを稼働させ、動作の正確性と安定性並びに耐久性に優れ小形化を実現する緩衝装置を提供する。【解決手段】扉Ａに固定される係り具８と、建具Ｂに固定される緩衝本体Ｃと、緩衝本体Ｃに回動可能に配備され係り具８に係脱する操作アーム７とからなり、緩衝本体Ｃはケース体１内に配備される固定ラックと、固定ラックに噛み合うピニオンを備え、操作アーム７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パ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成ることを特徴とする。【選択図】図１
