To provide a carrier device having a caster, in which a specific caster can be used and which can be prevented from overturning.SOLUTION: A carrier device having a cater comprises: a body part having a flat underside; a plurality of casters movable on a floor surface while kept mounted on the underside; and a mounting device disposed between the body part and each caster and used for mounting the body part and the caster. The body part has an internal thread part formed in the underside. The caster has: an external thread part projecting upward from the caster and helically engaged with the internal thread part; and a locking part disposed near the external thread part and configured to restrict rotation of the external thread part. The mounting device comprises a mounting-direction determination part that determines a direction in which the caster is mounted. The mounting direction determination part communicates with the internal thread part while kept mounted on the underside of the body part and has: a through-hole through which the external thread part passes; and a locked part that restricts rotation of the external thread part by its being locked to a locking part while the external thread part is helically engaged with the internal thread part by a predetermined amount.SELECTED DRAWING: Figure 6
【課題】特定のキャスターを使用することができ、且つ転倒の発生を抑制することができるキャスター付き搬送装置を提供する。【解決手段】キャスター付き搬送装置は、平坦な下面を有する本体部と、下面に取り付けられた状態で床面を移動可能とする複数のキャスターと、本体部、および、キャスターの間に配置され、本体部とキャスターとを取り付ける取付器具とを備え、本体部は、下面に形成された雌ネジ部を有し、キャスターは、当該キャスターから上方に突出して雌ネジ部と螺合する雄ネジ部、および、雄ネジ部の近傍に配置されて雄ネジ部の回転を規制する係止部を有し、取付器具は、キャスターの取り付け方向を決定する取付方向決定部を備え、取付方向決定部は、本体部の下面に取り付けられた状態で雌ネジ部と連通し、雄ネジ部が貫通する貫通孔と、雄ネジ部が雌ネジ部に所定量螺合した状態で係止部と係止して雄ネジ部の回転を規制する被係止部とを有する。【選択図】図6
