PROBLEM TO BE SOLVED: To provide a mechanism for restricting a moving amount of a stopper mechanism for a wheel in a simple method to solve problems associated with related arts including difficulty in releasing the stopper mechanism for the wheel, due to excessive biting (insertion).SOLUTION: In a mechanism for pressing brake shoes 8a, 8b against an outer periphery of a wheel 3, restricting parts 10a, 10b are installed near respective tips of the brake shoes, to allow the biting mounts to be set by changing a clearance between the wheel and themselves, so as to maintain the biting amounts constant.SELECTED DRAWING: Figure 1
【課題】車輪のストッパー機構において食い込み(挿し込み)過ぎたりして解除しづらいなどの従来技術の問題点を解決するためになされたもので、簡便な方法により車輪のストッパー機構の動き量を制限する機構の提供する。【解決手段】車輪3の外周にブレーキシュー8a、8bを当てて回転を止める機構において、ブレーキシューの先端付近に車輪との隙間を変えれば食い込み量の設定ができる制限具10a、10bを取り付け、食い込み量が一定になるように制限する。【選択図】図1
