PROBLEM TO BE SOLVED: To provide a runaway preventing device and a runaway preventing method capable of stably obtaining sufficient braking force.SOLUTION: A first braking mechanism 9 and a second braking mechanism 11 are provided in a traveling device 3. The braking force is directly or indirectly applied to a driving shaft 10 of a motor 6 in the first braking mechanism 9. The braking force is increased to maximum in a relatively short time and the braking force is directly or indirectly applied to an axle 7 of a wheel 5 in the second braking mechanism 11 such that the braking force is increased to maximum while spending a time longer than that of the first braking mechanism 9.SELECTED DRAWING: Figure 4
【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および逸走防止方法を提供する。【解決手段】走行装置3に第一ブレーキ機構9と第二ブレーキ機構11とを設置して、第一ブレーキ機構9でモータ6の駆動軸10に直接または間接に制動力を与え、比較的短時間でこの制動力を最大値まで増加させるとともに、第二ブレーキ機構11で車輪5の車軸7に直接または間接に制動力を与え、第一ブレーキ機構9よりも長い時間をかけてこの制動力を最大値まで増加させる。【選択図】図4
