To provide a vehicle coupling device that can prevent wheels or the like of a vehicle body and of a vehicle to be towed from digging the soft ground on which the vehicle body runs or digging a hole in the ground so as to rough the ground, when the vehicle body runs on the soft ground or the like while towing the vehicle to be towed.SOLUTION: A vehicle coupling device 3 is constituted of an annular rail 31 in a round shape which surrounds a vehicle body, a coupling arm 66 that extends from a vehicle to be towed and a coupling box 41 into which a tip 67 of the coupling arm 66 is inserted, where in the coupling box 41 are provided first rolling bearings 55 having outer rings 56 that rotate while contacting an outer peripheral surface 33 of the annular rail 31, second rolling bearings 58 having inner rings 60 that rotate while contacting an inner peripheral surface 32 of the annular rail 31, and third rolling bearings 61 having inner rings 63 that rotate while contacting the inner peripheral surface 32 of the annular rail 31.SELECTED DRAWING: Figure 3
【課題】車両本体が被牽引車両を牽引して柔らかな地面等の上を走行する際、車両本体や被牽引車両の車輪等が、走行する地面を掘り返したり、走行する地面に穴を掘る等して荒らすことを防止可能な車両連結装置を提供すること。【解決手段】車両本体を囲む円形の環状レール31と、被牽引車両から伸びる連結アーム66と、連結アーム66の先端67が挿入された連結箱41と、によって、車両連結装置3を構成し、連結箱41内に、環状レール31の外周面33に沿って接しつつ回転する外輪56を有する第1の転がり軸受55と、環状レール31の内周面32に沿って接しつつ回転する内輪60を有する第2の転がり軸受58と、環状レール31の内周面32に沿って接しつつ回転する内輪63を有する第3の転がり軸受61と、を設ける。【選択図】 図3
