To provide a towing device capable of easily connecting a dolly to a towing vehicle regardless of the form of the dolly and capable of easily restraining the dolly being towed and releasing the dolly being towed.SOLUTION: A towing device connected to a rear part of a towing vehicle so as to tow a dolly, comprises: a connection body connected to the towing vehicle; and a dolly surrounding bar including two side bars extending along respective side parts of the dolly and two rear bars continuous with the side bars and extending along respective corners of a rear part of the dolly, the dolly surrounding bar being movable, with the connection body as a fulcrum, between a position extending in a substantially upward direction at which the dolly is not towed and a position extending horizontally in a rearward direction at which the dolly is towed. By adjusting a distance between the two side bars, the dolly can be released or restrained. When the towing vehicle travels while the dolly surrounding bar surrounds the dolly along the side parts and the corners of the rear part of the dolly, the rear bar pushes the dolly from the rear part and tows the dolly in the traveling direction.SELECTED DRAWING: Figure 7
【課題】台車がどのような形態であっても容易に牽引車に台車を連結でき、台車の牽引時の拘束及び牽引からの解放が容易である牽引装置を提供する。【解決手段】牽引車の後部に接続配置されて台車を牽引する牽引装置であって、牽引装置は、牽引車との接続本体部と、台車の各側部に沿う二つの側部バー及びそれらに連続する台車の後部の各角部に沿う二つの後部バーを含む台車包囲バーとを含み、台車包囲バーは、接続本体部を支点として、略上方向に延びる台車を牽引しない時の位置と、後方向に水平に延びる台車牽引時の位置との間で移動可能である。また、二つの側部バー間の距離の調整により台車の解放・拘束が可能である。台車包囲バーが台車の側部と後部角部に沿って台車を包囲した状態で牽引車が進行すると後部バーが台車を後部から押して台車を進行方向に牽引する。【選択図】図7
