PROBLEM TO BE SOLVED: To provide a runaway arrester capable of obtaining stably sufficient brake force.SOLUTION: An engaging part 8 having an intersection surface 12a intersected with a rotation direction of a wheel 6 in a side view of the wheel 6 is fixed to the wheel 6, and a housing 9 is installed near the wheel 6, and a locking part 10 for regulating movement of the wheel 6 to the rotation direction is installed in the housing 9. Then, a movement mechanism 15 for moving at least either of the engaging part 8 and the locking part 10 to a standby position where the locking part 10 and the intersection surface 12a do not abut mutually, and to a working position where abutment is possible.SELECTED DRAWING: Figure 2
【課題】十分な制動力を安定的に得ることができる逸走防止装置を提供する。【解決手段】車輪6の側面視で車輪6の回転方向に交差する交差面12aを有する係合部8を車輪6に固定して、車輪6の近傍に筐体9を設置して、車輪6の回転方向への移動を規制されている係止部10を筐体9に設置して、係止部10と交差面12aとが当接しない待機位置と当接可能な作動位置とに、係合部8または係止部10の少なくとも一方を移動させる移動機構15を設置する。【選択図】図2
