PROBLEM TO BE SOLVED: To provide a simple locking mechanism of a machine structure as the locking mechanism of a falling prevention device.SOLUTION: An oscillation body 40 of a platform falling prevention device 10 is engaged with a primary driving end roller 27 linearly moved on a roller rolling surface 45 of a primary driving end part by a driving mechanism part 20, and engaged with a roller guide 66 of a follower slider 62 of a falling prevention plate 16 on a follower end roller 46 of a follower end part. The roller rolling surface 45 satisfies, when the falling prevention plate 16 in a projection completed state or a storage completed state, the geometric condition of setting the direction of the operation force F2 of a reverse direction transmitted from the falling prevention plate 16 side to move the oscillation body 40 in a direction orthogonal or roughly orthogonal to the linear motion of the primary driving end roller 27.SELECTED DRAWING: Figure 2
【課題】転落防止装置のロック機構として、機械構造のロック機構を簡素に実現すること。【解決手段】プラットホーム用転落防止装置１０の揺動体４０は、原動端部のローラ転動面４５にて駆動機構部２０により直線運動される原動端ローラ２７と係合し、従動端部の従動端ローラ４６にて転落防止板１６の従動スライダ６２のローラガイド６６と係合する。ローラ転動面４５は、転落防止板１６が突出完了状態及び収容完了状態であるときに、転落防止板１６側から伝達された揺動体４０を動かそうとする逆方向の作用力Ｆ２の方向を、原動端ローラ２７の直線運動と直交又は略直交する方向に作用させる幾何的条件を満たしている。【選択図】図２
