PROBLEM TO BE SOLVED: To obtain a rope coming-off preventing device equipped with a mechanism in which the gap between a rope guard and a rope can be easily confirmed and can be adjusted.SOLUTION: Provided are a fixing part (11) which is fixed to a lifting machine body, an adjusting bolt (13) in which a screwing quantity can be adjusted, a pair of guide bars (14) which are attached to the fixing part through mechanical springs (15), and a contact part (12) which is attached at the tips of the pair of the guide bars, includes a configuration so as to change the gap with the fixing part by moving in parallel against the fixing part, and is arranged as facing to the rope. The contact part is under a force in the direction of pulling each other with the fixing part by the mechanical springs, and, is pushed by the tip part of the adjusting bolt against the force of pulling each other corresponding to the magnitude of the screwing quantity of the adjusting bolt to change the gap, so that the gap with the rope can be adjusted to a predetermined value.SELECTED DRAWING: Figure 1

    【課題】ロープガードとロープの隙間を容易に確認し、調整可能とする機構を備えたロープ外れ止め装置を得る。【解決手段】巻上機本体に固定された固定部(11)と、締め込み量が調整可能な調整ボルト(13)と、機械ばね(15)を介して固定部に取り付けられる一対のガイド棒(14)と、一対のガイド棒の先端部に取り付けられ、固定部に対して並行に移動し、固定部との間隔を変化させる構成を有するとともに、ロープに対向配置される接触部(12)とを備え、接触部は、固定部との間で、機械ばねにより互いに引き合う方向に力が加わっており、調整ボルトの締め込み量の大きさに応じて、引き合う方向の力に逆らって調整ボルトの先端部で押されることで、間隔が変化し、ロープとの隙間を既定の値に調整可能とする。【選択図】図1
