PROBLEM TO BE SOLVED: To provide an armrest configured to pull out an operation cable from the vicinity of an axis of a pivot part to the inside of an armrest body, while adopting a structure including a turning regulation mechanism for regulating turning of the armrest body with respect to an armrest support body, and a chair.SOLUTION: A support structure includes a pivot part, and a cable insertion part 57. A turning mechanism includes a pivot part, and a bearing part 33a provided on an armrest body 16 and rotationally fitted to the pivot part inside the armrest body 16. A turning regulation mechanism has a turning regulation element in the armrest body 16 side and a turning regulation element in the support structure side. The turning regulation element in the armrest body 16 side and the turning regulation element in the support structure side are disposed at opposite positions, with an opening part 57a facing the inside of the armrest body 16, of the cable insertion part 57 and an axis o of the pivot part interposed therebetween.SELECTED DRAWING: Figure 4
【課題】肘掛け支持体に対する肘掛け本体の回動を規制する回動規制機構を有する構造を採用しつつも、枢軸部の軸心の近傍から操作ケーブルを肘掛け本体内に引き出すことができる肘掛け、及び、椅子を提供する。【解決手段】支持構造体は、枢軸部と、ケーブル挿通部57と、を有している。回動機構は、枢軸部と、肘掛け本体16に設けられ、肘掛け本体16の内部で枢軸部に回動可能に嵌合される軸受部33aと、を有している。回動規制機構は、肘掛け本体16側の回動規制要素と支持構造体側の回動規制要素とを有している。肘掛け本体16側の回動規制要素と支持構造体側の回動規制要素は、ケーブル挿通部57の肘掛け本体16内に臨む開口57aと枢軸部の軸線oを挟んで相反する位置に配置されている。【選択図】図4
