PROBLEM TO BE SOLVED: To provide a rotary handrail device having a handrail member which can rotate around a rotary shaft, that appropriately prevents a fall of a handrail member because of its own weight without using any special damper mechanisms, and continues to ensure resistance appropriate for rotation of a handrail member even if it is used for a long period.SOLUTION: A rotary handrail device 1 includes a base member 2 and a handrail member 3 journaled to the base member 2. A washer 40 is interposed between a clamping plate 13A of the base member 2 and a base end member 5 of a handrail member 4, and grease is provided in a spiral wire shape groove 45 formed on a base member side one surface 43 of the washer 40. A projection 44 is provided on a handrail member side one surface 42 of the washer 40, and the washer 40 is fixed to the handrail member 4 by fitting the projection 44 into a fitting hole 25 formed in the handrail member 4.SELECTED DRAWING: Figure 4
【課題】 回転軸周りで旋回可能な手摺り部材を備えた回動式手摺り装置において、特別なダンパー機構を用いずに手摺り部材の自重落下が適切に防止されるとともに、長期間にわたって使用された場合でも、手摺り部材の回動に適切な抵抗が確保され続ける回動式手摺り装置を提供する。【解決手段】 回動式手摺り装置１は、ベース部材２と、ベース部材２に対して軸支された手摺り部材３を備える。ベース部材２の挟持板１３Ａと手摺り部材４の基端部材５の間には、ワッシャー４０が介装されるとともに、ワッシャー４０のベース部材側片面４３に形成された渦巻線状溝４５には、グリスが設けられる。ワッシャー４０の手摺り部材側片面４２には突起部４４が設けられ、突起部４４が手摺り部材４に形成された嵌合孔２５に嵌合することにより、ワッシャー４０は、手摺り部材４に対して固定される。【選択図】 図４
