To provide a technique for achieving an elevation type platform fence for preventing a child from passing through and giving easy recognition to a blind person by reducing a gap between a rope at the lowest part and a platform, and providing a smooth elevating operation of the rope and good visibility from a conductor.SOLUTION: In an interval adjustment mechanism part 50 of an elevation type platform fence 2, 1) a plurality of links 64 are connected in a polygonal line shape, 2) a guide part 63 guides vertical movement while every other joint part 65 supports each of blockage parts 6, 3) the joint part 65 of the uppermost end is fixed at a predetermined position, and 4) the joint part 65 of the lowermost end is connected to a driving belt 33. The driving belt 33 is put around a driving pulley 31, and upper driven pulleys 42, 43 and lower driven pulleys 44, 45 in an elevation part 20.SELECTED DRAWING: Figure 4 【課題】最下部のロープとホームとの隙間を減らし、子供の通り抜け防止や盲人からの認識が容易で、ロープの昇降動作も滑らかで車掌からの視認性も良い昇降式ホーム柵を実現する技術を提供すること。【解決手段】昇降式ホーム柵２の間隔調整機構部５０は、１）複数のリンク６４が折れ線状に連結され、２）１個おきのジョイント部６５が遮断部６を１本ずつ支持しつつガイド部６３で上下方向への移動が案内され、３）最上端のジョイント部６５が所定位置で固定され、４）最下端のジョイント部６５が駆動ベルト３３に連結されている。駆動ベルト３３は、駆動プーリ３１と、昇降部２０内の上部従動プーリ４２，４３並びに下部従動プーリ４４，４５と、に掛け回されている。【選択図】図４
