PROBLEM TO BE SOLVED: To provide an inexpensive traction carriage, switchable to a stabilizing state of the movement in the traction direction and an unrestricted state in the movement direction.SOLUTION: The lower end of a steering caster 8 is positioned above the lower end of a rotary caster 3 in a state of being rotated so that its axle 6a is positioned above the inclined axis Y1, on the one hand, contacts with the ground surface F by jumping out downward from the lower end of the rotary caster 3 in a state of rotating the steering caster 8 so that its axle 6a is positioned under the inclined axis Y1, and is thereby set so as to separate the rotary caster 3 from the ground surface F while contacting a fixed caster 7 with the ground surface F by inclining a carriage body 2 so that its traction directional front side is positioned upward.SELECTED DRAWING: Figure 4

    【課題】牽引方向への移動が安定する状態と移動方向に制限のない状態とに切替可能な低コストな牽引台車を提供する。【解決手段】操舵キャスター8の下端は、その車軸6aが傾斜軸心Y1より上方に位置するよう回動させた状態で、回動キャスター3の下端より上方に位置する一方、操舵キャスター8をその車軸6aが傾斜軸心Y1より下方に位置するよう回動させた状態で、回動キャスター3の下端より下方に飛び出して地面Fに接触することにより、台車本体2をその牽引方向前側が上方に位置するよう傾けて固定キャスター7を地面Fに接触させるとともの回動キャスター3を地面Fから離間させるよう設定される。【選択図】図4
