To provide a towing car in which a towing device for towing a carriage is arranged at a rear part thereof, which can easily surround and restrain a carriage when towing the carriage and release the carriage from the towing car, with an extreme simple mechanism.SOLUTION: A towing device comprises carriage surrounding bars including two side part bars that are disposed along side parts of a carriage and two rear part bars leading to the side bars that are disposed along the inside from corner parts at a rear part of the carriage. Respective end parts at the towing car-side of the two side part bars are mounted on the towing device, so that respective tips of the two rear part bars can be moved between an inside position and an outside position at the rear part of the carriage. When the carriage is released, the respective tips of the two rear part bars move to the outside position at the rear part of the carriage so that the carriage can be released from the carriage surrounding bars. When the carriage is towed, the respective tips of the two rear part bars move to the inside position at the rear part of the carriage to surround the carriage along the side parts of the carriage and the corner parts at the rear part of the carriage. When the towing car runs forward, the rear part bars push the rear part of the carriage to be able to tow the carriage in a forward running direction.SELECTED DRAWING: Figure 6
【課題】台車を牽引するための牽引装置を後部に配置し、台車の牽引時の包囲・拘束及び台車の牽引車からの解放を極めて簡単な機構で容易に行える牽引車を提供する。【解決手段】牽引装置は、台車の各側部に沿える二つの側部バー、及びそれらに連続する台車の後部の各角部から内側に沿える二つの後部バーを含む台車包囲バーを備え、牽引装置には二つの側部バーの牽引車側の端部の各々が取り付けられ、二つの後部バーの各々の先端が、台車の後部における内側の位置と外側の位置の間で移動可能であり、台車解放時には、二つの後部バーの各々の先端が台車の後部の外側の位置に移動して台車を台車包囲バーの外に解放でき、台車牽引時には、二つの後部バーの各々の先端が台車の後部の内側の位置に移動して台車の側部と後部の角部から内側に沿って台車を包囲し、牽引車の進行により後部バーが台車を後部から押すことで台車を進行方向に牽引できる。【選択図】図6
