PROBLEM TO BE SOLVED: To provide a caster arrangement structure of an article with a caster and a carriage having the same structure which is easy to push even at an uneven or unlevel place, and can travel by stably keeping a predetermined speed.SOLUTION: A caster arrangement structure of an article 1 with a caster includes the caster 20 arranged on a lower surface 13 of a main body part 10, and thereby the main body part 10 can move freely. The caster 20 includes a support member 21 attached to the main body part 10 and supporting a wheel 22. The support member 21 includes a hinge part 30 on a front side in a travel direction A, and a rear side in the travel direction A around the hinge part 30 vertically moves. Biasing means 45 biasing in a direction B of separating the main body part 10 and the support member 21 is arranged on a rear side of the hinge part 30. When an impact C is applied from the front side to a lower side part of the wheel 22, the support member 21 rotates around the hinge part 30 against biasing force of the biasing means 45, and the support member 21 on the rear side of the hinge part 30 moves upward D.

    【課題】凹凸や段差のある箇所でも押し易く、安定して所定の速度を保って走行させることができるキャスタ付物品のキャスタ配設構造及び当該構造を備えた台車を提供する。【解決手段】本体部10の下面13にキャスタ20が配設され、これにより本体部10が移動自在とされたキャスタ付物品1のキャスタ配設構造で、キャスタ20は、本体部10に取り付けられて車輪22を支持する支持部材21を有し、支持部材21は、進行方向Aの前側にヒンジ部30を有し、ヒンジ部30を中心として進行方向Aの後側が上下動し、本体部10と支持部材21とが離間する方向Bに付勢する付勢手段45がヒンジ部30の後側に設けられ、車輪22の下側部分に前側から衝撃Cが加えられたときに、付勢手段45の付勢力に抗してヒンジ部30を中心として支持部材21が回動し、ヒンジ部30の後側の支持部材21が上方Dに移動する。【選択図】図3
