Summary:PROBLEM TO BE SOLVED: To structure in high structural strength, an expansion position holding mechanism which suppresses the change of an expansion position of an armrest even when a backrest angle of a seatback is changed.SOLUTION: An expansion position holding mechanism 10 which suppresses angel change of the expansion position of an armrest 5 to a floor F even when a backrest angle of a seatback 2 is changed includes: a link member 11 connected in a state so as to swing and rotate around a rotation axis 11A onto the floor F; and a pin 12 provided in a position shifted from a support shaft 5A of the armrest 5 and inserted into a long hole 11B formed in the link member 11. The pin 12 is brought into contact with an end part 11B1 of a long hole 11B by the expansion of the armrest 5 so as to regulate the expansion position of the armrest 5, and even when the seatback 2 is backward inclined, the link member 11 is pressed by the pin 12 and rotated in a form of separating the end part 11B1 of the long hole 11B from the pin 12, with this, the position of the armrest 5 can be corrected in the expansion direction to become close to an expansion angle before backward inclining.SELECTED DRAWING: Figure 2 【課題】シートバックの背凭れ角度が変えられてもアームレストの展開位置の変化を抑える展開位置保持機構を、構造強度の高い構成とすること。【解決手段】アームレスト５の展開位置をシートバック２の背凭れ角度が変えられてもフロアＦに対する角度変化を抑える展開位置保持機構１０は、フロアＦ上に対して回転軸１１Ａのまわりに揺動回転できる状態に連結されたリンク部材１１と、アームレスト５の支軸５Ａからずれた位置に設けられてリンク部材１１に形成された長孔１１Ｂ内に差し込まれたピン１２とを有する。アームレスト５の展開によりピン１２が長孔１１Ｂの端部１１Ｂ１と当接することでアームレスト５の展開位置が規制され、シートバック２が後傾してもリンク部材１１がピン１２に押されて長孔１１Ｂの端部１１Ｂ１をピン１２から引き離す形に回転することでアームレスト５が展開方向に位置補正可能となって後傾前の展開角度に近づけられる。【選択図】図２
