PROBLEM TO BE SOLVED: To move a bag naturally by smoothly oscillating universal casters while reducing their damage against a strong shock load.SOLUTION: The bag with casters has a handle installed in the bag part that is self-supporting, with a plurality of universal casters 1 fixed on the bottom face. In each of the universal caster 1, a yoke 7 with a wheel 6 connected is connected to a fixed part 10 through a pivot 9 and a ball bearing 8. Between the yoke 7 and the fixed part 10, there is provided a deformation prevention gap 20 where the two are brought into contact with each other in a state where the pivot 9 is displaced by a load acting on the bag part and where the two are in a non-contact state in a state where no load is acting on the bag part. The fixed part 10 has integrally formed therein, with plastic molding, an inner cylinder 8A in which an outer wheel 8B of the ball bearing 8 with the pivot 9 inserted into the inner wheel 8A is fixed inside, a plurality of vertical ribs 13 which are radially fastened on the outside of the inner cylinder 8A, an outer cylinder 8B which is formed by fixing the outer peripheral end of the vertical ribs 13 to the inside thereof, and a bottom plate 14 which is fixed to the inner cylinder 8A and the outer cylinder 8B.SELECTED DRAWING: Figure 7

    【課題】強い衝撃荷重に対して自在キャスターの損傷を少なくしながら、スムーズに首振りさせて無理なく移動する。【解決手段】キャスターを有する鞄は、複数の自在キャスター1を底面に固定して自立するバッグ部に取っ手を設けている。自在キャスター1は、車輪6を連結したヨーク7を旋回軸9とボールベアリング8を介して固定部10に連結しており、ヨーク7と固定部10との間に、荷重が作用して旋回軸9が変位する状態で互いに接触し、荷重が作用しない状態で非接触状態となる変形阻止隙間20を設けている。固定部10は、旋回軸9が内輪8Aに挿入されたボールベアリング8の外輪8Bを内側に固定してなる内筒8Aと、内筒8Aの外側に放射状に固定してなる複数の垂直リブ13と、垂直リブ13の外周端を内側に固定してなる外筒8Bと、内筒8Aと外筒8Bとに固定してなる底プレート14とをプラスチックで一体的に成形している。【選択図】図7
