間された位置にあって、メンテナンスを行い易くする。When the load is carried on the cargo bed 8, the support rod 9 can be removed from the lower surface of the cargo bed 8 and tilted to form a transmission cover for covering the upper side surface of the transmission belt 5. By shortening the dump cylinder 6 in this state, the loading platform 8 is laid down around the dump hinge 7. or,
When lowering the load on the loading platform 8, the dump cylinder 6 is extended to rotate the loading platform 8 upright around the dump hinge 7. When inspecting or repairing the transmission belt 5, the engine 2, the transmission case 4 and the like under the platform 8, the dump cylinder 6 is extended to stand the platform 8 around the dump hinge 7, and then the support rod 9 is attached. It is erected and supported on the lower surface of the loading platform 8. When performing maintenance work in this state,
Even if the dump cylinder 6 is shortened for some reason, since the loading platform 8 is supported by the frame 1 by the support rod 9, there is no danger of the loading platform 8 moving unexpectedly. At this time, the support rod 9 is located apart from the transmission belt 5 to facilitate maintenance.

ことがない。As described above, the support rod 9 for supporting the dumping posture of the loading platform 8 is in a standing position capable of preventing the loading platform 8 from being lowered during maintenance work around the power transmission belt 5, and thus safe maintenance can be performed. You can do it, and when you fall, you can use the transmission belt 5.
The structure can be simplified by covering the portion and also used as a transmission cover, and since the opening and closing as a transmission cover is also performed by raising and lowering the support rod 9, the operation can be performed easily. Further, during maintenance work, the transmission belt 5 is often removed, and for this purpose, the transmission cover / support rod 9 needs to be raised, so that the support rod 9 does not forget to support the luggage carrier 8.

The front chassis 13 can be steered by a driver's seat 10 and a steering wheel 12. With a pair of left and right front wheels 11, etc., it is possible to carry and maneuver. Further, the rear chassis 15 has a swing shaft 14 in the up-down direction and a rolling shaft 27 in the front-rear direction at a connecting portion of the front part of the frame 1 in the front-rear direction to the front chassis 13, and is swingable in the left-right direction. And, it is connected to the left and right in a freely tiltable manner. This rear chassis 15
Is above the frame 1 having a pair of left and right rear wheels 3,
There is a loading platform 8 which is vertically swung up and down around a dump hinge 7 at a rear end portion, and a hydraulic dumping cylinder 6 is provided between a frame 1 and a lower surface of the loading platform 8. Ups and downs.

起伏を行わせることができる。The frame 1 is provided with an engine 2, a transmission case 4 having a gear mechanism transmitted from the engine 2 through a transmission belt 5, a hydraulic pump 17 transmitted by a belt 16, and the like. The front wheels 11 can be driven by transmitting the left and right rear wheels 3 from within the mission case 4 and the gear mechanism in the front wheel transmission case 19 via the front wheel take-out shaft 18. Further, 20 is a fuel tank and 21 is a battery. By driving the engine 2, the rear wheels 3 are driven through the transmission belt 5, the gear mechanism in the transmission case 4, and the front wheels 11 are further driven from the front wheel take-out shaft 18 through the gear mechanism in the front wheel transmission case 19. As a result, four-wheel drive is possible. When the hydraulic pump 17 is driven by the transmission of the belt 16, the hydraulic lever of the dump cylinder 6 is switched by operating the dump lever 22 on the side of the driver's seat 10 to expand and contract the dump cylinder 6 to raise and lower the platform 8. Can be done.
