Description
そして、前記キャスターには移動機能と一緒に一定の場所で動かずに安定的に支持するために高さ調節機能が付加されたものがある。
したがって、前記車輪110の周面が地面に接触されて前記重量物20を所望の位置に容易に移動させることができる。
一方、前記支持体300は、地面に接触されるように前記開口部120を介して前記キャスター本体100に出没可能に備えられる。
以上に構成された本発明のレベルキャスター10は、図3及び図4を参照して、参考にして動作関係を説明する。
上記のように構成された本発明を提供することで、ユーザーの回転操作だけで誰でも簡単、迅速にキャスターの高さを調節することができるという利点がある。
