  Furthermore, a fuel tank 16 is attached to the outer surface of the chassis frame 3.

  Next, the operation of the above embodiment will be described.

  When configured as described above, the first extension rail 4 and the second extension rail 5 and the cross member 6 are supported between the chassis frames 2 and 3 so as to extend in the width direction of the vehicle 1 as in the prior art. On the other hand, even if the lengths of the first extension rail 4 and the second extension rail 5 are increased in order to meet the further extension request of the bodywork in the field, the first extension rail 4 and the second extension rail 5 And the rear wheel RT can be prevented from interfering with each other, and the extension member 7 can be removed and supported on the chassis frames 2 and 3 while the extension member 7 is attached to the actual use position. (Refer to Fig. 1) There is no need to transport, and there is no need to worry about rising transportation costs.

Further, no special bracket is required, and only the first L-shaped bracket 8 and the second L-shaped bracket 9 having simple shapes are used, and the first extension rail 4 and the second extension rail 5 and the rear wheel RT are used. Thus, it is possible to support the extension member 7 while avoiding the interference, and it is also possible to avoid an increase in man-hours for managing special parts.

  Incidentally, in the case of the present embodiment, when the vehicle 1 is transported, as shown in FIGS. 7, 8 and 9, the right outer tire 11 is removed from the double tires constituting the rear wheel RT and the upper surface of the chassis frame 2 is removed. Even when the left outer tire 12 is removed and placed on the upper surface of the chassis frame 3, the first extension rail 4 and the second extension rail 5 interfere with the tire 11, or the cross member 6 becomes the tire 12. It is effective in reducing the lateral width of the vehicle 1 and further reducing the transportation cost.

  Further, since the first extension rail 4 and the second extension rail 5 and the cross member 6 are arranged on the chassis frames 2 and 3 on the front side of the vehicle 1 with respect to the brake lamp 15, the vehicle 1 is transported when the vehicle 1 is transported. Even when it is necessary to actually travel the vehicle, the first extension rail 4, the second extension rail 5 and the cross member 6 do not block the brake lamp 15 that is lit during braking, which hinders traveling. No worries.

  In this way, even if the lengths of the first extension rail 4 and the second extension rail 5 are increased, the extension member 7 can be reliably supported on the chassis frames 2 and 3 without using special parts. Management man-hours can be reduced.

  The vehicle extension member support structure for transporting a vehicle according to the present invention is not limited to the above-described embodiment, and the cross member is mounted on the chassis frame when interference with other members becomes a problem. It is possible to carry the vehicle by mounting it on the feet of the passenger seat of a cab (not shown) without being mounted on the vehicle, and various other modifications can be made without departing from the scope of the present invention. Of course.
