PROBLEM TO BE SOLVED: To allow operation of attachment/detachment operation of a hanger suspending and supporting a retractor and movably provided along a rail to/from the rail on the ground to reduce work cost.SOLUTION: A fall prevention device is movably provided with a hanger 10 suspending and supporting a retractor along a guide groove 6 of a rail 1, and is provided with a stopper member 40 in an end part of the rail 1. A string-equipped ring 60 is hanged on a hook 51 provided in a tip part of an operation rod 50, the string-equipped ring 60 is re-hanged on a bent piece 42a provided in a tip part of an upper side plate part 42 of the stopper member 40, the stopper member 40 is swung by pulling-down of a string 61 hanging down from the ring 60, and the tip of a lower side plate part 43 is evacuated outside the guide groove 6 to bring it into an open state. A pair of facing engagement frame parts 52 provided in the tip part of the operation rod 50 is engaged with both side edge parts of the hanger 10, and the hanger 10 is extracted from the opening end of the rail 1 and is put down onto the ground by operation to pull the operation rod 50. 【課題】リトラクタを吊下げ支持し、レールに沿って移動自在に設けられたハンガーのレールに対する着脱操作を地上において操作できるようにして、作業コストの低減を図ることである。【解決手段】レール１のガイド溝６に沿ってリトラクタを吊下げ支持するハンガー１０を移動自在に設け、レール１の端部にストッパ部材４０を設ける。操作棒５０の先端部に設けられたフック５１に紐付きリング６０を掛け、その紐付きリング６０をストッパ部材４０の上側板部４２の先端部に設けられた折曲げ片４２ａとの間で掛け替えを行ない、リング６０から垂れ下がる紐６１の引き下げによりストッパ部材４０を揺動させ、下側板部４３の先端をガイド溝６の外側方に退避させて開放状態とする。操作棒５０の先端部に設けられた対向一対の係合枠部５２をハンガー１０の両側縁部に係合し、操作棒５０を引く操作によりハンガー１０をレール１の開口端から抜き取って地上に下ろす。【選択図】図６
