To provide a caster which can travel even if an obstacle such as a stone exists.SOLUTION: A caster includes an attachment shaft 8, a holder 9, a wheel 10, and a leaf spring 4. The wheel 10 is pivotally supported on the holder 9. The holder 9 is located below the attachment shaft 8 and has a wheel axis 11 at a position which offsets relative to the attachment shaft 8 to a rear side as viewed in a travel direction. The leaf spring 4 is bent, one side piece 12 is attached to a lower side of the attachment shaft 8, and the other side piece 13 is attached to an upper surface of the holder 9.SELECTED DRAWING: Figure 2
【課題】 石などの障害物があっても走行可能なキャスターの提供。【解決手段】 取付軸８とホルダ９と車輪１０と板バネ４を備え、車輪１０は、ホルダ９に軸支してあり、ホルダ９は、取付軸８の下方に位置し、取付軸８に対して進行方向後側にずれた位置に車輪の軸１１を有し、板バネ４は、屈曲しており、一方の片１２が取付軸８の下に取付けてあり、他方の片１３がホルダ９の上面に取付けてある。【選択図】 図２
