PROBLEM TO BE SOLVED: To provide a traveling device of a transportation vehicle, capable of reducing a wheel width of the transportation vehicle.SOLUTION: In a traveling device 1 of a transportation vehicle 100 which is aligned in the longitudinal direction and the width direction of a cargo base 101, and travellably constitutes the cargo base 101, an arm 2 is turnably supported to the lower part of the cargo base 101 at its upper end, and an axle box 3 is supported to the lower part of the arm 2 so as to be vertically oscillatory. A wheel 6 is supported to an axle 5 while having a center face I crossing an oscillation face S of the axle 5 arranged in the axle box 3. By this arrangement, by forming the arm 2 by taking into consideration the width of the wheel 6, the radius of a turning trace of the arm 2 can be reduced, and a pitch of the traveling device 1 aligned in the lower part of the cargo base 101 can be reduced. As a result, the wheel width L2 of the transportation vehicle 100 can be reduced. |
