To provide a traveling dolly that is less likely to limit load, enables stable conveyance, furthermore, less likely to limit a direction of movement, and able to turn in a relatively small radius.SOLUTION: The traveling dolly includes: an even number of vertical steering shafts 11 provided at equal intervals on a lower part of a dolly P; a horizontal axle 12 bent from a lower part of each vertical steering shaft 11 and extending an outward extending direction in a plan view; a traveling wheel 2 that is mounted on an extremity of each horizontal axle 12 and drivable around the horizontal axle; and a regulating mechanism 4 that regulates the extending direction of the horizontal axle 12 of the traveling wheel 2. Using a reaction force against the ground, a driven traveling wheel 2A varies a steering direction in which a drive axle extends. By exerting control so as to vary a steering direction in which adjacent horizontal axles 2A extend in directions opposite to each other by an equal rotational phase opposite to each other, the steering direction is varied, with the moment always balanced in the entire dolly.SELECTED DRAWING: Figure 4

    【課題】荷重制限がかかりにくく、また安定して運搬でき、さらに移動方向に制限がかかりにくく、比較的小回りが利く走行台車を提供する。【解決手段】台車Pの下部に等間隔に設けられた、偶数本の垂直方向の垂直操舵軸11と、各垂直操舵軸11の軸下部から屈曲して設けられた、平面視外方への伸長方向へ伸長する水平車軸12と、各水平車軸12の先に取り付けられた、水平車軸周りに駆動可能な走行輪2と、前記走行輪2の水平車軸12の伸長方向を規制する規制機構4とを具備する。駆動した走行輪2Aが地面との反力によって駆動車軸の伸長方向たる操舵方向を可変させるものであり、隣り合う水平車軸2Aは互いに相反する方向へ、互いに相反する等しい回転位相だけ伸長方向たる操舵方向を可変させるよう制御することで、台車全体でモーメントが常に釣り合った状態で操舵方向を可変させる。【選択図】図4
