PROBLEM TO BE SOLVED: To provide a technology of a movable fence which performs vertical movement smoothly and quickly with a simple structure.SOLUTION: A movable fence 10 includes: two support post parts 20; a restraining bar 40 provided so as to move vertically between the support post parts 20; and a driving part 60 which drives the restraining bar 40 to move vertically. The support post parts 20 include a support post body 21 and a guide rail 22. The restraining bar 40 has a first restraining bar 41a and a second restraining bar 41b. The driving part 60 includes an engagement chain 61, a motor 62, and a chain housing box 63. When the restraining bar 40 is moved upward, the engagement chain 61 is engaged and extended in a column shape by operation of the motor 62. With the movement, the first restraining bar 41a moves upward.

    【課題】簡易的な構成で柵の上下動を円滑に速やかに行う可動柵の技術を提供する。【解決手段】可動柵10は、二つの支柱部20と、支柱部20間を上下に移動可能に架設された制止バー40と、制止バー40の上下に移動させる駆動部60とを備える。支柱部20は、支柱本体21とガイドレール22とを備える。制止バー40は、第1の制止バー41a及び第2の制止バー41bを有している。駆動部60は、噛み合いチェーン61と、モーター62と、チェーン収容ボックス63とを備える。制止バー40を上方に移動させる場合は、モーター62の動作によって、噛み合いチェーン61が噛み合わさって柱状になりつつ伸長する。その動作に伴い、第1の制止バー41aが上方向に移動する。【選択図】図1
