The body 2 can be easily transported and moved forward or backward. Further, by rotating the housing 2 around the axis of the wheel 42, the orientation of the housing 2 with respect to the floor surface (the posture of the power generation device 1) can be changed. And the electric power generating apparatus 1 is a state with the 1st mounting attitude | position (1st use attitude | position) which made the outer surface of the floor part 3 the lower surface which opposes a floor surface, and the housing | casing 2 as shown in FIG. Is selected from a second mounting posture (second usage posture) that is inclined at a predetermined angle (in this embodiment, for example, 90 degrees in this embodiment) and the outer surface of the rear wall portion 6 is a lower surface facing the floor surface. Thus, the mounting posture can be switched.

As shown in FIG. 4, the floor portion 3 includes a pair of first leg portions that support the housing 2 together with the wheels 42 in the first placement posture (first use posture), in addition to the movement mechanism portion 51. 44, 44. Note that, similarly to the above description, unless otherwise specified, the configuration will be described in the vertical direction and the front-rear direction in the first placement posture (first usage posture).

First leg 44 is provided at a front end side of the floor portion 3 projects downward, it abuts against the first mounting postures (the first use position) at the floor. Therefore, the first leg portion 44 that is brought into contact with the floor surface, the housing 2 can be supported against the floor by the

first leg portion

44, 44 and the wheel 42. And this power generator 1 inclines the housing | casing 2 back (it inclines back) from the 1st mounting attitude | position (1st use attitude | position) by using the axle 43 as a fulcrum, and makes the

1st leg parts

44 and 44 from a floor surface. By separating, it becomes a transportable posture that can be moved, and can be transported via the moving mechanism 51 (that is, a posture tilted, for example, by about 30 degrees from the state of the first use posture).

The rear wall 6 has a second leg 45 that supports the housing 2 together with the wheels 42 in the second placement position (second use position), and a movement operation unit 46 for performing a movement operation during transport movement. And have. As in the above description, unless otherwise defined, the configuration will be described in the vertical direction and the front-rear direction in the first placement posture (first usage posture).

The movement operation unit 46 includes two rod-

like portions

47 and 47 projecting upward from the rear wall portion 6 and a bridging portion 48 connecting the upper ends of the rod-

like portions

47 and 47, and each rod-like portion 47 extends upward. The protrusion amount can be adjusted, and the bridging portion 48 has a gripping surface that is gripped by the user.

Therefore, when switching to the transporting posture, it is possible to change the posture of the housing 2 by gripping the moving operation unit 46, and the posture can be easily switched. And the housing | casing 2 can be pulled around via the movement operation part 46, and the wheel 42 can be drive | worked, and it becomes easy to carry and move the housing | casing 2. FIG. Further, by changing and adjusting the protruding amount of each rod-like portion 47 to be small, it is difficult for the movement operation unit 46 to obstruct the use of the power generation device 1 at times other than during transportation movement such as use as an external power source. Can do.

As shown in FIG. 4, the second leg portion 45 protrudes rearward and is provided on the upper end side of the rear wall portion 6. As shown in FIG. 5, the second leg portion 45 is on the floor surface in the second placement posture (second use posture). Abut. Therefore, the housing 2 can be supported with respect to the floor surface by the second leg portion 45 and the wheel 42 by bringing the second leg portion 45 into contact with the floor surface. Further, the power generation device 1 tilts the housing 2 forward (tilt forward) from the second mounting posture (second usage posture) with the axle 43 as a fulcrum, and separates the second leg portion 45 from the floor surface. And it becomes a carrying posture. Therefore, the transport posture is an intermediate posture that is generated when switching between the first placement posture (first use posture) and the second placement posture (second use posture).

The left wall 8 further includes a power generation operation unit such as a power switch 49 for externally operating the power generation operation of the power generation unit 12. Therefore, the power generation apparatus 1 starts the power generation operation of the power generation unit 12 when the power switch 49 is turned on and is turned off during the power generation operation, thereby stopping the power generation operation. The power generation operation is continued until the cutting operation is performed.

The power generator 1 configured as described above has the following operational effects. In the definition of the front-rear direction, the description that does not specify the posture is the first placement posture (first use posture), and the description that specifies the posture conforms to the specified posture.

By providing the moving mechanism portion 51 at the rear end of the floor portion 3, the posture change of the housing 2 is restricted in the rotation direction of the wheels 42, and the mounting surface of the housing 2 is the outer surface and the rear wall of the floor portion 3. It is defined as two surfaces facing the circumferential direction of the axle 43 with the outer surface of the portion 6. Therefore, the power generation device 1 has a predetermined angle (in this embodiment, for example, from the first mounting posture (first usage posture) with the outer surface of the floor 3 being the lower surface and the state in which the housing 2 is in the first usage posture. 90 degrees) and a second mounting posture (second usage posture) that is inclined and has the outer surface of the rear wall 6 as a lower surface.

The two

inclined surfaces

20, 20 inclined toward the supply path 22 are provided on the first inner surface 16 and the second inner surface 17, so that the fuel liquid is supplied to the supply port 23 in each mounting posture and moving posture. The fuel liquid can be easily supplied in a stable manner. And since it becomes easy to maintain the upstream opening of the supply path 22 in the state covered with the fuel liquid at the time of each mounting posture, movement posture, and attitude change, gas such as air in the tank 15 does not easily enter the supply path 22. This makes it difficult to cause malfunction due to gas mixture in the flow path on the fuel liquid side. Furthermore, by providing the receiving port 27 of the power generation unit 12 at the front end of the upper surface of the case 26, the fuel liquid in the power generation unit 12 hardly flows back to the receiving port 27 at the time of each mounting posture, moving posture, or posture change.

Further, as shown in FIG. 4, the liquid storage unit 11 is disposed above and in front of the power generation unit 12 with reference to the first placement posture (first use posture). When changing to the mounting posture (second usage posture), the liquid storage unit 11 is positioned above and behind the power generation unit 12 with reference to the second mounting posture (second usage posture). For this reason, even if the power generation device 1 is changed to a backward-moving posture, the liquid storage unit 11 is always located above the power generation unit 12. Therefore, it is possible to supply the fuel liquid by the weight of the fuel liquid (gravity) from the liquid reservoir 11 to the power generation unit 12, the fuel fluid supply to the power generation portion 12 can be performed with a simple configuration. Then, it is possible to perform the abolition or low output of the fuel drawing device for sucking fuel liquid from the liquid reservoir 11, it is possible to reduce the weight and size reduction and production cost of the generator 1.

It is possible to facilitate connection. Then, while the rotatable body portion 33 of the output section 14 with respect to the housing 2, the axis of the rotary shaft 34 by disposing substantially in parallel with the axle 43, by rotating the main body portion 33, connected The direction of the surface 35 can be switched between the direction toward the floor 3 and the direction toward the rear wall 6. Therefore, when the outdoor surface is used in rainy weather, the connection surface 35 is directed outwardly of the front and rear housings 2 or obliquely downward and downward, so that the connection surface 35 can be prevented from being exposed to rainwater. It becomes easy to avoid malfunction.

Further, by providing the exhaust port 39 and the air supply port 36 on the outer wall portion (side wall portion) that is not easily blocked in any mounting posture, it is difficult to cause malfunction or malfunction due to the blockage of the exhaust port 39 or the like. it can. And by providing the power generation operation part in the outer wall part (left wall part 8) which is not easily blocked in any mounting posture, it comes into contact during transportation movement compared to those provided in the front wall part 5 and the rear wall part 6. It becomes difficult to be blocked at the time of mounting as compared with those provided on the floor 3 and the rear wall 6.

Note that the inclined surface 20 may be inclined in different directions for each position on the inner surface. For example, as shown in FIG. 6, in the modified example, the supply path 22 is located at the approximate center of the ridge line, protrudes rearward from the second inner surface 17, the first inner surface 16 has the inclined surface 20 facing rearwardly downward, and The first inner surface 16 is inclined downward from the side end toward the center in the left-right direction. Therefore, located substantially at the center is the lowermost ridge is connected to the supply passage 22 in the position can be easily allowed to flow into the supply port 23 by its own weight to the fuel liquid in the tank 15. Further, the inclined surface 20 is not limited to a planar shape, and may be a curved shape. Further, the inclined surface 20 may be combined with a plurality of inclinations in a stepped shape or the like.
