To smoothly rotate a thrust bearing without using a lubricant, prevent the rotation of the thrust bearing from being spoiled due to a weight of a movable body, make a price cheap and give durability, and prevent turning performance from worsening even after using for a long term.SOLUTION: A caster 1 includes a wheel 10, a support frame 12, a pivot 13, and a thrust bearing 20. The caster 1 is such that: the thrust bearing 20 has an upper substrate 21, a lower substrate 22, and many balls 23 held between the upper substrate 21 and the lower substrate 22; the balls 23 comprise metallic balls 23s and resin balls 23p; the balls 23 are arranged so that the adjacent balls roll while being in contact with each other; and the metallic balls 23s and the resin balls 23p are arranged so as to prevent the metallic balls 23s from being adjacent to each other.SELECTED DRAWING: Figure 1

    【課題】潤滑剤を使用しなくてもスラストベアリングが円滑に回転し、移動体の重量によりスラストベアリングの回転が損なわれることもなく、安価で耐久性があり、長期間使用しても旋回性能が悪くならないようにする。【解決手段】車輪10、支持フレーム12、旋回軸13、スラストベアリング20を備えたキャスター1であって、スラストベアリング20は、上側基板21と、下側基板22と、上側基板21と下側基板22の間に保持された多数のボール23を備え、ボール23は、金属ボール23sと樹脂ボール23pからなり、ボール23は隣接するボール同士が接触しながら転がるように配置され、かつ、金属ボール23sが隣接しないように、金属ボール23sと樹脂ボール23pが配置されているキャスター1。【選択図】図1
