In the above-described embodiment, the case where the loading device B is installed in the vehicle and the cylinders 5 and 5 are installed in the loading device B has been described. However, when only the rear confirmation is intended, the gap L There is no problem even if the cylinders 5 and 5 are provided and directly loaded and fixed directly on the balance weight 4 of the vehicle. Further, as shown in FIG. 2, the siphon tube 33a is extended to near the bottom of each of the cylinders 5 and 5, and the LP
Although the gas can be sent to the carburetor through the fuel hose 35 in the liquefied state, it can be discharged in the vaporized state by forming the siphon pipe 33a of one of the cylinders 5 short to the position that becomes the gas portion. You can also do valve 3
By selecting the opening / closing of 3, LP gas in a liquefied state and a vaporized state can be sent to the carburetor. In this way, since the LP gas from the cylinder can be selected to either the liquefied state or the vaporized state, when the carburetor does not sufficiently vaporize the liquefied LP gas when the temperature is low, the valve 33 is selected. The vaporized LP gas can be supplied to the engine through the carburetor, and the engine can be started easily. Then, after the temperature of the carburetor is raised, the LP gas can be used even in the liquefied state.

FIG. 6 is an exploded perspective view of a loading apparatus according to another embodiment, and FIG. 7 is a usage drawing. In this embodiment, only the back plate 9 is used as a support for the cylinder, and the bottom plate 7 is inclined. The present embodiment is the same as the above embodiment except that the stopper 28 is provided instead of the chain that regulates the range of angles, and only different points will be described. The members corresponding to those in FIGS. 4 and 5 are designated by the same reference numerals. A back plate 9 serving as a support is fixed to the bottom plate 7 at the rear end of the bottom plate 7 by fixing its lower end to the flange portion 7a formed at the rear end of the bottom plate 7. The back plate 9 has a notch at a portion corresponding to the gap L between the cylinders in order to widen the visual field to the rear and further remove the blind spot. Fixing devices C are provided on the left and right sides of the back plate 9, respectively. That is, the tightening bands 15 and 15 are rotatably attached via the hinges 14, and the fastener 16 is connected to the tip end thereof. On the other hand, the fastener 1
A hook 17 is rotatably attached to a position corresponding to 6 via a hinge 18. Therefore, the cylinders 5 and 5 are loaded on the left and right sides of the bottom plate 7, respectively, and the tightening band 1
When 5 is rotated around the barrel of the cylinder and the fastener 16 is engaged with and locked by the hook 17, the cylinders 5 and 5 are fixedly supported by being pressed against the back plate 9 side through the tightening action of the tightening band 15. It Further, stoppers 28, 28 are attached to the left and right ends of the bottom plate 7 and the attachment substrate 6, respectively.
The stopper 28 has two end portions of two link rods 28a and 28b that can be bent in a double-fold shape at a predetermined angle, and a flange portion 7c formed at both end portions of the bottom plate 7 and a flange portion of the mounting substrate 6, respectively. It is provided by rotatably pivoting with respect to 6c. Therefore, when inspecting the engine portion, the loading device B can be rotated backward by tilting the bottom plate 7 with the hinge 21 as a fulcrum, and the bottom plate 7 can be tilted within a predetermined angle range. Then, the bottom plate 7 is stopped via the stopper 28, and the stacking device B can be held at the rotating position. Therefore, the driver's seat 3 can be tilted without hitting the loading device B.

In each of the above embodiments, the chain 23 and the stopper 2 are used.
Although the range of the inclination angle of the bottom plate 7 is regulated by 8,
These are for preventing the loading device B from falling more than necessary. Therefore, instead of the chain 23 and the stopper 28, a locking piece or the like for stopping the bottom plate 7 when the bottom plate 7 is inclined at a predetermined angle can be attached at an appropriate position of the balance weight 4. Further, although the back plate 9 and the partition plate 10 as the support are plate-shaped ones, there is no problem as long as the cylinder 5 can be fixedly supported. Therefore, for example, as shown in the rear view of the main part of FIG. 8 (the same members as those in FIG. 2 are denoted by the same reference numerals), columnar support rods 11 are welded to the bottom plate 7 in accordance with the number of cylinders 5 installed. And the cylinder 5 by means of a fixture C attached to the support rod 11.
Can also be supported and fixed. Also, the bottom plate 7 does not have to be formed of a single plate, and may be formed separately for each cylinder. Further, the means for fixing the cylinder 5 is not limited to the method described above, and it is possible to fix the cylinder 5 via a plurality of support rods standing upright around the cylinder 5 to restrict the lateral movement of the cylinder 5. It may be. In this fixing method, when the bottom plate 7 is inclined, in order to prevent the cylinder 5 from coming off the support rod, the cylinder 5 is fixed by the ring-shaped fixing tool C or the pressure is extended between the support rods. It goes without saying that it is desirable to press and fix the shoulder portion and the like of the cylinder 5 with a tool.

[0012]

According to the present invention, the operator can see the rear of the vehicle through the gap between the fuel gas cylinders, so that the blind spot is reduced and the safety of the vehicle during traveling is improved. . Further, since the bottom plate can be tilted, it is not necessary to remove the loading device each time the engine part is inspected, which is convenient. Further, since the LP gas can be supplied from the cylinder in the liquefied state and the vaporized state, the engine can be easily started even when the temperature is low.
