To provide a slide structure of a movable armrest of a chair which has high freedom degree of movement and less restriction.SOLUTION: There is provided a slide structure of a movable armrest of a chair where an elbow rest 13 can slide on an elbow rest reception part 12 of an elbow support 11 fixed to a chair body side. Between the elbow rest reception part 12 and the elbow rest 13, a slide structure 14 is provided for slidably supporting the elbow rest 13 with respect to the elbow rest reception part 12. One guide groove 19 is provided on the elbow rest 13, and the other guide groove 20 is provided on the elbow rest reception part 12. A stationary shaft 17 for relatively moving in the guide groove 19 of the elbow rest 13 is provided on the elbow rest reception part 12 side, and a movable shaft 18 for moving with the elbow rest 13 in the guide groove 20 of the elbow rest reception part 12 is provided on the elbow rest 13 side. Movement is applied to the elbow rest by relative movement of the plurality of shafts 17, 18 in the plurality of guide grooves 19, 20.SELECTED DRAWING: Figure 3 【課題】動きの自由度が高く制限が少ない椅子の可動肘のスライド構造にする。【解決手段】椅子本体側に固定される肘支柱１１の肘当て受部１２の上を肘当て１３が摺動可能な椅子の可動肘のスライド構造において、肘当て受部１２と肘当て１３との間に、肘当て受部１２に対し肘当て１３をスライド可能に支持するスライド機構１４を構成し、肘当て１３に一方のガイド溝１９を、肘当て受部１２に他方のガイド溝２０をそれぞれ分けて備える一方、肘当て受部１２側に肘当て１３のガイド溝１９内を相対移動する固定軸１７を、肘当て１３側に肘当て受部１２のガイド溝２０内を肘当て１３と共に移動する可動軸１８をそれぞれ備え、複数のガイド溝１９，２０内を複数の軸１７，１８が相対移動することによって肘当てに動きが与えられるようにしている。【選択図】図３
