PROBLEM TO BE SOLVED: To suppress increase in slide resistance of an operation cable, while suppressing enlargement of an armrest, and suppress a change in operability of an operating member by movement of an armrest body in an armrest (a furniture component) of a chair movably supporting an armrest body (a second structure) to a support structure (a first structure) and linking a prescribed functional part via the operation cable to the operating member supported by the armrest body.SOLUTION: An armrest body 8b includes movable bodies (a base member 8m and a cover member 8s) longitudinally movable with respect to a support rod, and a stationary body (a turning member 8n) longitudinally immovable with respect to the support rod. The stationary body locks a lock end portion 9a1 of an outer cable 9a and a lock end portion 9b1 of an inner cable 9b. The movable body includes an inner pull-out length retaining mechanism 8X that changes a wiring route of the inner cable 9b in longitudinal movement to suppress a change in the pull-out length of the inner cable 9b.SELECTED DRAWING: Figure 12
【課題】支持構造体(第一構造体)に肘掛け本体(第二構造体)を移動可能に支持し、かつ肘掛け本体に支持した操作部材には操作ケーブルを介して所定の機能部位を連係させた、椅子の肘掛け(什器部品)において、肘掛けの大型化を抑えながら、操作ケーブルの摺動抵抗の増加を抑え、かつ肘掛け本体の移動による操作部材の操作性の変化を抑える。【解決手段】肘掛け本体8bは、支持杆に対して前後移動可能な移動体(ベース部材8mおよびカバー部材8s)と、支持杆に対して前後移動不能な固定体(回動部材8n)と、を備え、固定体は、アウターケーブル9aの係止端部9a1およびインナーケーブル9bの係止端部9b1を係止し、移動体は、前後移動時にインナーケーブル9bの配索経路を変化させてインナーケーブル9bの引き出し長さの変化を抑えるインナー引き出し長さ維持機構8Xを備えている。【選択図】図12
