To provide a four-node rotation mechanism that can obtain a deceleration effect both when opening and closing a lid without imposing restrictions on design of the lid.SOLUTION: A four-node rotation mechanism used to open and close a lid, includes: a link, one end of which is connected to a rotary shaft A of the lid; a link b one end of which is connected to a rotary shaft B of the other end of the link a; a link c one end of which is connected to a rotary shaft C of the other end of the link b and provided with a gear at its other end; and a link d one end of which is connected to a rotary shaft D of the gear and the other end of which is a fixed link connected to the rotary shaft A of the lid; and a unidirectional rotary damper which engages with the gear and has viscous resistance to rotation in one direction. And a position of dead center as of when the link c is a prime mover node, is included within a movable range of the lid.SELECTED DRAWING: Figure 3
【課題】蓋のデザインに制約を生じさせることなく、蓋を開くときおよび閉じるときの双方において減速効果を得ることができる四節回転機構を提供する。【解決手段】蓋の開閉に用いられる四節回転機構であって、その一端が前記蓋の回転軸Ａに接続されるリンクａと、その一端が前記リンクａの他端の回転軸Ｂと接続されるリンクｂと、その一端がリンクｂの他端の回転軸Ｃと接続され、その他端に歯車を設けたリンクｃと、その一端が前記歯車の回転軸Ｄと接続され、その他端が前記蓋の回転軸Ａと接続される固定リンクであるリンクｄと、前記歯車と咬み合い、１方向の回転に対して粘性抵抗を有する１方向性ロータリーダンパーを含み、前記蓋の可動域内に前記リンクｃを原動節とした場合の死点の位置が含まれる。【選択図】図３
