To make it possible to store a handrail device appropriately in an upper surface part even when a protruding object, which protrudes upward from the upper surface part, exists.SOLUTION: A handrail device 30 includes a support part 41 and a handle part 57. The support part 41 is rotatably mounted on an upper surface part 15. The handle part 57 is rotatably mounted on the support part 41. The support part 41 is arranged along the upper surface part 15 when the handle device 30 is in a handle-stored state 30E. The handle part 57 is configured to be arranged directly above a protruding object 20 in a gap S57e of the protruding object 20 in a state of being folded with respect to the support part 41 when the handrail device 30 is in the handrail-stored state 30E.SELECTED DRAWING: Figure 6

    【課題】上面部から上側に突出する突出物が存在しても、上面部に手摺装置を適切に格納できるようにする。【解決手段】手摺装置30は、支持部41と持手部57とを備える。支持部41は、上面部15に回転可能に取り付けられる。持手部57は、支持部41に回転可能に取り付けられる。支持部41は、手摺装置30が手摺格納状態30Eのときに、上面部15に沿うように配置される。持手部57は、手摺装置30が手摺格納状態30Eのときに、支持部41に対して折り畳まれた状態で、突出物20との間に隙間S57eをあけて突出物20の真上に配置されるように構成される。【選択図】図6
