PROBLEM TO BE SOLVED: To provide a technology capable of realizing a movable fence at low cost without restriction to stopping accuracy of a vehicle or a vehicle having a different door position.SOLUTION: A movable fence 1 is installed in a box-shaped fence housing part 95 provided on a platform 90, and is composed of three retractable fences which are a first fence 10, a second fence 20 and a third fence 30 different from one another in height. In the first fence 10, when two fold-down support post parts 15a and 15b change from a closed state to an open state, that is, from an inverted state to a fallen state, they fall in opposite direction to each other by the same amount. As a result, an elongation/contraction barrier central part 11 and elongation/contraction barrier outside parts 12a and 12b move downward while maintained horizontal. Like the first fence 10, the second fence 20 and the third fence 30 move downward while maintained horizontal.
【課題】車両の停止精度や異なる扉位置の車両に対して、制限を受けることなく低コストで実現可能な可動柵の技術を提供する。【解決手段】可動柵１は、プラットフォーム９０に設けられた箱状の柵収容部９５に設置されており、第１の柵１０、第２の柵２０、第３の柵３０の３つの高さが異なる可倒柵から構成されている。第１の柵１０において、二つの可倒支柱部１５ａ、１５ｂは、閉じた状態から開いた状態、つまり倒立した状態から倒れた状態になる場合に、相対する方向に同じ量だけ倒れる。その結果、伸縮バリア中央部１１、伸縮バリア外側部１２ａ、１２ｂは水平を維持しつつ下降する。第２の柵２０及び第３の柵３０は、第１の柵１０と同様に水平を維持しつつ下降する。【選択図】図１
