Summary:To provide a caster capable of shielding a radial outside of a screw shaft by an operation ring for operating a screw shaft, and preventing careless rotation of the screw shaft through the operation ring by a simple structure and furniture with a caster.SOLUTION: A caster comprises: a fitting base 11; a wheel support block 13; a screw shaft 16; a female screw part 17; an operation ring 18; a wheel 14; and a lock mechanism 35. The wheel support block 13 is rotatably supported to a pivot shaft 12. The screw shaft 16 extends upward coaxially from the pivot shaft 12. The female screw part 17 is provided on the fitting base 11 and screwed to the screw shaft 16. The operation ring 18 is arranged to surround a radial outside of the screw shaft 16 and integrally coupled to the screw shaft 16. The wheel 14 is supported to the wheel support block 13. The lock mechanism 35 locks simultaneously, rotation of the wheel 14 and rotation of the wheel support block 13 to the pivot shaft 12.SELECTED DRAWING: Figure 3 【課題】簡単な構成により、ねじ軸を操作する操作リングによってねじ軸の径方向外側を遮蔽でき、かつ、操作リングを通したねじ軸の不用意な回転を防止できるキャスター、及び、キャスター付き什器を提供する。【解決手段】キャスターは、取付ベース11、車輪支持ブロック13、ねじ軸16、雌ねじ部17、操作リング18、車輪14、ロック機構35を備えている。車輪支持ブロック13は、枢軸12に回転可能に支持される。ねじ軸16は、枢軸12から同軸に上方に延びる。雌ねじ部17は、取付ベース11に設けられ、ねじ軸16に螺合される。操作リング18は、ねじ軸16の径方向外側を取り囲んで配置され、ねじ軸16に一体に結合される。車輪14は、車輪支持ブロック13に支持される。ロック機構35は、車輪14の回転と枢軸12に対する車輪支持ブロック13の回転を同時にロックする。【選択図】図3
