To provide a rolling swivel caster having improved drive followability capable of moving smoothly a carriage in a driving direction, by a method having a principle different from a conventional improvement plan.SOLUTION: A rolling swivel caster is constituted so that a wheel 8 of a caster following steering by trail gets complete 2-degree rolling pair, and a tread shape of the wheel is constituted so that a vertical distance between a caster base 1 and a wheel grounding spot becomes geometrically unique and constant in order that the wheel 8 is operated in the complete 2-degree rolling pair.SELECTED DRAWING: Figure 1

    【課題】従来の改善策とは原理の異なる方法で、駆動した方向に台車を円滑に移動させることができる駆動追従性を向上させた転がり旋回キャスターを提供する。【解決手段】トレールによって転舵追従するキャスターの車輪8が完全な2自由度の転がり対偶となるように構成するとともに、車輪8が完全な2自由度の転がり対偶で動作するためにキャスターベース1と車輪接地点の垂直距離が幾何学的に一意かつ一定になるように車輪のトレッド形状を構成した。【選択図】図1
