To cause a towed vehicle equipped with a traction gear to trace a track substantially similar to that of a towed vehicle during retreating or backing of a traction vehicle and to reduce a direction switching distance (switching space) to a linear motion during the backing or the retreating.SOLUTION: A towed vehicle lacking active steering performance for connection to a traction vehicle comprises: a front wheel attachment plate provided in the towed vehicle and having a front wheel attached thereto; an arm extending forward from the towed vehicle and having a hole into which an engaging pin of the traction vehicle can loosely fit and which is formed at a tip; a vertically extending shaft member fixed at one end to the arm and rotatably fixed at the other end to the front wheel attachment plate; a set of gear members one of which is fixed to the other end of the shaft member and the other of which is fixed to the front wheel attachment plate; and a towed vehicle side abutment positioned on a front surface side of the shaft member. While the towed vehicle retreats, the towed vehicle side abutment abuts against the traction vehicle side abutment of a rear end of the traction vehicle to retreat the towed vehicle on a same track.SELECTED DRAWING: Figure 6
【課題】牽引装置を備える被牽引車両が、牽引車両の後退または後進時に被牽引車両と実質的に同じ軌跡を辿るようにする、および後進または後退時の直線動への方向切換距離(切換スペース)を低減する。【解決手段】牽引車両に連結する能動操向性を有しない被牽引車両は、被牽引車両に設けられ前輪を取り付ける前輪取付板と、被牽引車両から前方に延び、牽引車両の係止ピンが遊嵌可能な穴が先端部に形成されたアームと、一端がこのアームに固定され他端が前輪取付板に回動可能に固定された、上下方向に延びる軸部材と、一方は軸部材の他端部に、他方は前輪取付板に固定された1組の歯車部材と、軸部材の前面側に位置する被牽引車両側当接部とを備える。被牽引車両の後退時には、被牽引車両側当接部が牽引車両の後端部の牽引車両側当接面に当接して同じ軌道を後退する。【選択図】 図6
