PROBLEM TO BE SOLVED: To provide a transportation dolly which minimizes an inner wheel difference, inhibits wobbling to left and right sides during movement, and flexibly follows a step or an irregularity on a ground surface to stably maintain its posture.SOLUTION: A transportation dolly 1 includes: a loading space 2; universal wheels 31; a swing frame 4; a fixed wheel 32; and a damper 5. The swing frame 4 swings a swing part 42 positioned at a center part of the loading space 2 in a vertical direction H. The fixed wheel 32 is provided on a lower surface of the swing part 42 of the swing frame 4. The damper 5 is formed so as to utilize viscosity resistance of a fluid to bias the swing part 42 of the swing frame 4 downward.SELECTED DRAWING: Figure 1

    【課題】内輪差を極力なくすとともに、移動時の左右へのふらつきを抑えることができ、地面における段差又は凹凸に対しても柔軟に追従して、姿勢を安定して保つことができる搬送台車を提供すること。【解決手段】搬送台車1は、荷台2、自在車輪31、揺動フレーム4、固定車輪32及びダンパ5を備えている。揺動フレーム4は、荷台2の中央部に位置する揺動部42を上下方向Hに揺動させる。固定車輪32は、揺動フレーム4の揺動部42の下面に設けられている。ダンパ5は、流体の粘性抵抗を利用して揺動フレーム4の揺動部42を下方へ付勢するよう構成されている。【選択図】図1
