PROBLEM TO BE SOLVED: To securely lock a wheel to prevent unexpected movement in a wheel stopper.SOLUTION: In a wheel stopper, a stopper bracket 11 is provided at a base part 3, at which a wheel 2 is rotatably provided, and a stopper plate 12 which vertically moves relative to the base part 3 (the stopper bracket 11) while maintaining a horizontal state to switch its position between a stationary position A and an open position B is provided. Multiple protrusions 13a are disposed at the wheel 2 in a circumferential direction. Engagement openings 12b, which engage with the protrusions 13a when the stopper plate 12 is in the stationary position A to make the wheel 2 incapable of rotating, are provided in the stopper plate 12.SELECTED DRAWING: Figure 1
【課題】車輪ストッパにおいて、車輪を確実にロックして予期せぬ移動を防止する。【解決手段】車輪2が回転可能に設けられたベース部3にストッパブラケット11を設け、水平状態を保ったままベース部3(ストッパブラケット11)に対して上下移動して静止位置Aと開放位置Bとに切換可能なストッパプレート12を設ける。車輪2に周方向に複数の突起13aを配置する。ストッパプレート12に静止位置Aにあるときに突起13aに係合し、車輪2を回転不能にする係合用開口12bを設ける。【選択図】図1
