2 are provided with pulleys 501 and 502, respectively, and the belt 5
03 is wrapped, and tensioner 504 is installed in the middle of the belt.
Apply tension to the belt by applying tension to the tensioner 5.
The support arm 506 of the shaft 505 of 04 is supported at the end of the upper mounting table 201. As described above, the power transmission member 5 is configured, the shafts are connected, and the engine 3
The generator 4 is operated to generate electricity. The back cover plate 105 on this side is made removable for maintenance of the power transmission section.

A vertically elongated cassette-type fuel tank 6 is housed and mounted on the empty space on the opposite side of the generator 4 on the upper piece 201 forming the upper mounting base, and in the embodiment, this side of the base frame 1 A shelf 601 is provided on the piece 103,
The shelf section 601 is designed to be able to accommodate the tank 6 in a removable manner from the front side, and the shelf section 601 is provided with raised pieces 602 on the back side and sides to regulate the lower circumferential surface of the tank, and the shelf section 601 has raised sections 602 on the back side and sides to regulate the lower circumferential surface of the tank. There is a hook 603 on the middle upper part of the
is provided and is engaged with a locking portion 604 provided on the inner surface of the side piece 103 to be locked to the wall surface. The tank 6 is located above the engine 3, so fuel is supplied by gravity, and a simple fuel supply system is sufficient.

As described above, all the components including the engine 3, generator 4, their power transmission system 5, and fuel tank 6 are housed in the box-shaped base frame 1 so as to be isolated from the outside, and when viewed externally, there are It is shaped like a vertical box with a lid.

By the way, there are top and bottom cover plates 106 on the front of the base frame 1.
As shown in FIG. 3, FIG. 7, and FIG.
11... are formed approximately to the full width in the left and right direction. On the front side of the slit 111...
1..., the protruding cover piece 11 is pushed out to the front and hangs downwardly at an angle, opening downward.
2... are provided on each slit surface, and the upper ends of the cover pieces 112... are continuous with the cover plate 106. An opening/closing plate 113 faces the back side of the upper front cover plate 106, and the opening/closing plate 113 is provided with the same number of slits 114 of the same pitch as the slits 111 in parallel and spaced apart vertically.
Blind portions 115 are formed between the slits 114.
Fold the upper end of the opening/closing plate 113 to the back side and attach the upper receiving piece 1.
16, and a spring 11 is installed between the receiving piece 116 and the upper edge piece 106a bent and extending to the back side of the upper end of the cover plate 106.
7 is interposed, and on the other hand, at the bottom of the opening/closing plate 113, a lower edge piece 106 is provided by bending the lower end of the cover plate 106 to the back side.
b is provided with a stopper 118 that comes into contact with it when lowering, and the lower end 119 of the opening/closing plate 113 faces outward and downward from the hole 106c provided in the lower edge piece 106b, and is bent and extended to the back side at the upper end of the lower front cover part 107. When the lid is closed, it abuts against the upper edge piece 107a formed by the upper edge piece 107a, and is thereby prevented from moving downward by the spring 117. FIG. 7 shows a state in which the lower cover plate 107 is closed.
5... coincides with slit 111... and slit 11...
1... is closed. Therefore, intrusion of rainwater and dust from the outside world is prevented, and mischief such as inserting a wire or the like through the slits 111 is also prevented.

By the way, the lower cover plate 107 is opened as shown in FIG. 1, and the recoil starter knob 304 is pulled and operated to start the engine 3 and operate the generator 4. In this case, the generator 4 also has heat, Requires cooling. By opening the lower front cover plate 107, the above-mentioned opening/closing plate 113 opens the upper edge piece 107 of the lower end portion 119.
The restraint by a is released, the spring 117 and its own weight move downward, and the stopper 118 is held at the lower limit of movement in contact with the upper surface of the lower edge piece 106b of the upper cover plate 106,
The slits 114 and 111 coincide and communicate with the outside world, allowing cooling air to be taken in and hot internal air to be discharged.

By the way, the base frame 1 described above is installed permanently, for example, by being attached to a pole or a wall surface, and in the embodiment, support members 701 and 702 made of angle materials are arranged symmetrically in parallel and folded into an L shape as shown in the second figure. The base frame 1 is bent and parallel to each other and regulated to a predetermined width by cross members 703, one side piece and the lower piece of the base frame 1 are supported and fixed, and the base frame 1 is mounted and supported on a pole or a wall.

FIG. 9 shows a modified embodiment of the invention.

In this embodiment, there is a support plate 1 on top of the generator 4 in the base frame 1.
A fuel tank 12 is disposed and supported on the fuel tank 12, and an LP gas cylinder is used in this embodiment.Therefore, an engine 3 whose specifications have been changed for use with LP gas is used. The height is larger than in the example.

As is clear from the above, according to the present invention, a generator,
Because the internal combustion engines are placed above and below, the area occupied is dramatically smaller than before, making it possible to install the generator in areas with space constraints.
In addition to the effect of further improving the practicality of this type of generator, the outside is surrounded by a box-shaped frame to isolate it from the outside world, making it possible to protect it from rainwater, dust, and even mischief.

Further, according to the present invention, when in use, the lower cover on the recoil starter side is opened to operate the internal combustion engine,
When inspecting the engine, open one or both of the lower covers, and when inspecting the generator or refueling, open either or both of the upper covers. Depending on the situation, only the necessary parts inside the case can be opened. Can be opened wide.

Furthermore, according to the present invention, since the ventilation hole is provided in the upper part of the case, hot air from the upper part of the case can be effectively discharged during use.In addition, since the internal combustion engine is located at the bottom and the fuel tank is located at the top, the fuel It has many advantages, such as the fact that the supply system uses a gravity type and is simple and sufficient.
