FIG. 4 is a diagram showing a fixing method of the fixing band 1 in the first embodiment of the present invention.
When the fuel tank 100 is fixed to the oil guard 102 using the fixing band 1 having the above structure, first, the fuel tank 100 is placed on the fuel tank support member 104 of the oil guard 102 and the fixing band 1 is fixed. Are arranged from both sides in the width direction of the fuel tank 100 to the upper surface along the periphery of the fuel tank 100. And the 1st fixing tool 6 and the 2nd fixing tool 8 of the fixing band 1 are made to oppose, and at least one part of the 2nd fixing tool 8 is the upper surface part 18 of the 1st fixing tool 6, and the cylindrical base part 14. The bolt 10 is passed through the bolt holes 20, 22, 24, and 26 and is tightened with the bolt 10 so as to be housed while being covered with the side surfaces.

  When tightening the bolt 10, as shown in FIG. 4, the second fixing tool 8 is housed in the space on the tip side from the partition portion 16 of the first fixing tool 6, and the bolt 10 is It is preferable to hold the first fixture 6 with another spanner 30. At this time, since the side surface and the upper surface portion 18 of the first fixing tool 6 cover the side surface and the upper surface of the second fixing tool 8, the second fixing tool 8 is provided around the longitudinal axis of the first fixing tool 6. The movement is restricted and the fixing band 1 is not twisted.

  As the bolt 10 is tightened, the first fixing tool 6 and the second fixing tool 8 are arranged in the direction in which the upper ends approach each other in the width direction axis, specifically, the first fixing tool 6 and the second fixing tool. Attempts to rotate around the width axis passing through the tip and bottom of each of the eight. Here, in this rotation, the lower surface of the bolt hole 20 and the upper surface of the bolt hole 22 of the first fixture 6, the upper surface of the bolt hole 26 of the second fixture 8, and the lower surface of the bolt hole 24 remove the bolt 10. By pushing, a bending moment is generated in the bolt 10. However, in the present embodiment, when the second fixing tool 8 tries to rotate, the upper surface of the second fixing tool 8 is in contact with the upper surface portion 18 of the first fixing tool 6. The tool 8 is prevented from rotating. Further, when the first fixing tool 6 tries to rotate, the upper surface portion 18 of the first fixing tool 6 is in contact with the upper surface of the second fixing tool 8, so that the first fixing tool 6 rotates. Is also prevented. Therefore, in the present embodiment, the upper surface portion 18 of the first fixing tool 6 functions as a rotation preventing means for preventing the first fixing tool 6 and the second fixing tool 8 from rotating.

According to the present embodiment configured as described above, the following excellent effects can be obtained.
The upper surface portion 18 is provided on the first fixing tool 6, and the upper surface portion 18 comes into contact with the upper surface of the second fixing device 8 so that the upper portions of the first fixing device 6 and the second fixing device 8 are close to each other. It is possible to prevent the rotation in the direction to be performed. Therefore, when the bolt 10 is tightened, the corner portions of the first fixture 6 and the second fixture 8 are prevented from coming into contact with the fuel tank 100 and the band portions 2, 4 are prevented from floating away from the surface of the fuel tank 100. The fuel tank 100 can be securely fixed to the oil guard 102 without loosening. Therefore, the fixing structure of the present embodiment can realize a strong structure. For example, even when the fuel tank 100 receives a large inertia force due to a sudden brake applied when the engine working machine is carried on the vehicle, the fixing band 1 is The fuel tank 100 can be firmly held without loosening.
Further, by preventing the upper surface portion 18 from rotating, the load exerted on the bolt 10 from the inner walls of the bolt holes 20, 22, 24, 26 can be reduced, thereby suppressing the bending moment generated in the bolt 10. Therefore, the bending of the bolt 10 can be prevented.

In the conventional L-shaped fixture, if the fixture rotates when the bolt is tightened, the corner of the fixture may hit the fuel tank and damage the fuel tank 100 as shown in FIG. In order to protect this, it is necessary to take measures such as arranging a rubber plate member between the fixture and the fuel tank.
In the present embodiment, since the upper surface portion 18 of the first fixture 6 can prevent the first fixture 6 and the second fixture 8 from rotating, the fuel tank is fixed by the fixing structure of the fixing band 1. The risk of damage can be reduced, and the need for placing a rubber plate member between the fixed structure and the fuel tank is reduced.

  Since the first fixture 6 and the second fixture 8 are formed in a substantially rectangular parallelepiped, the fixing structure can be strengthened. That is, in the conventional L-shaped fixing tool, the portion raised from the band is deformed by tightening the bolt, and a sufficient fixing force cannot be obtained. In the present embodiment, since the fixing structure is strengthened, deformation of the fixing structure can be effectively prevented, and therefore, the bolt 10 can be sufficiently tightened. Can be securely fixed.

  The first fixture 6 is provided with two bolt holes 20 and 22, and the second fixture 8 is also provided with bolt holes 24 and 26. Therefore, when the first fixing tool 6 and the second fixing tool 8 try to rotate when the bolt 10 is tightened, the first fixing tool 6 and the second fixing tool 8 are respectively connected to the bolt 10 at two points. Because of the abutment, this structure can also suppress the rotation of the first fixture 6 and the second fixture 8, and the fuel tank 100 can be reliably fixed by the fixing band 1.

Since the first fixing tool 6 and the second fixing tool 8 are each formed in a substantially rectangular parallelepiped, when the first fixing tool 6 and the second fixing tool 8 are fixed to each other with the bolt 10, the spanner 30 or the like Therefore, it is easy to hold the first fixture 6 and the fixing work of the fixing band can be easily and reliably performed.
Here, FIG. 5 and FIG. 6 are diagrams showing a fixing method using a fixing structure of a conventional fixing band. As shown in FIG. 5, in the conventional L-shaped fixture 200, in order to prevent the fixtures 204 and 206 and the band 208 from being twisted when the bolt 202 is tightened, a thin plate-like shape standing from the band 208 is used. The part and the bolt 202 are fixed with the spanners 210 and 212, and then the nut (not shown) is tightened with the further spanner 214, or the bolt 202 and the nut (not shown) as shown in FIG. ) Is held by the spanners 212 and 214, and the nuts are tightened. When the fixtures 204 and 206 are twisted, the fixtures are grasped by the spanner 210 and returned to the original position as shown in FIG. 6B. Such a complicated work was necessary.

  As described above, in the conventional L-shaped fixture 200, when the opposing fixtures 204 and 206 are tightened with the bolts 202, the thin plate-like portion standing from the band 208 of the fixture 200 is held by the spanner 210. Therefore, it was very difficult to hold the fixture 200. In this embodiment, since the 1st fixing tool 6 and the 2nd fixing tool 8 are each formed in the substantially rectangular parallelepiped, the 1st fixing tool 6 can be hold | maintained easily and reliably with the spanner 30 grade | etc.,.

  In the present embodiment, the second fixture 8 is covered with the upper surface portion 18 of the first fixture 6 and the side surfaces of the cylindrical base portion 14, and the first fixture 6 and the second fixture 8. Is formed in a substantially rectangular parallelepiped, it is possible to prevent the second fixture 8 from rotating about the longitudinal axis with respect to the first fixture 6. Therefore, the first fixing tool 6 and the second fixing tool 8 can be prevented from being twisted during the fixing work of the fixing structure, and the fixing band 1 can be prevented from being twisted. Thereby, the fixing work of the fixing structure can be performed easily and in a short time.

[Second Embodiment]
Next, a fixing structure for a fuel tank fixing band according to a second embodiment of the present invention will be described. FIG. 7 is a perspective view of the fixing structure of the fixing band 50 in the second embodiment, and FIG. 8 is a cross-sectional view of the fixing structure of the fixing band 50 in the second embodiment.
As shown in FIGS. 7 and 8, the fixing structure of the fixing band 50 in the second embodiment is provided in the first fixing tool 52, the second fixing tool 54, and the first fixing tool 52. And a rotation preventing member 56 for preventing the second fixing tool 54 from rotating.

The first fixing member 52 is configured by a substantially rectangular parallelepiped, that is, a tubular portion having a rectangular cross section, with an upper surface and a distal end surface being opened. A bolt hole 58 through which the bolt 53 is inserted is formed in the surface of the proximal end side 52 </ b> A of the first fixture 52. On both side surfaces of the first fixture 52, a hole 60 through which the rotation preventing member 56 is inserted is formed in the upper portion on the distal end side.
The second fixture 54 is also configured by a substantially rectangular parallelepiped, that is, a cylindrical portion having a square cross section, with an upper surface and a tip surface opened. Bolt holes 62 through which the bolts 53 are inserted are formed on the surface of the proximal end side 54 </ b> A of the second fixture 54. On both side surfaces of the second fixture 54, a protruding portion 64 that protrudes upward from the side surface is formed at the upper portion on the distal end side. A nut 65 is welded to the surface of the base end side 54 </ b> A of the second fixture 54 at a position that coincides with the bolt hole 62.

The rotation preventing member 56 is constituted by a bolt, is inserted into the hole 60 of the first fixing member 52, and is attached to the first fixing member 52 by screwing with the nut 66.
Here, in the present embodiment, the position of the rotation preventing member 56 is such that the lower end of the rotation preventing member 56 abuts on a portion other than the protruding portion 64 on the upper surface of the second fixture 54 or is below a predetermined value. It is set to a position having a distance.

When the fuel tank 100 is fixed using the fixing band 50 having the fixing structure as described above, it is performed as follows.
First, the distal end portion of the second fixture 54 is inserted into the first fixture 52. In this state, at least the tip side of the side surface and the bottom surface of the second fixture 54 is covered with the side surface and the bottom surface of the first fixture 52, and the tip portion of the second fixture 54 is the first fixture. 52. With the protrusion 64 of the second fixture 54 positioned closer to the proximal end 52A of the first fixture 52 than the hole 60 of the first fixture 52, the rotation preventing member 56 is fixed to the first fixture 52. It is inserted into the hole 60 of the tool 52 and fixed with a nut 66. In this state, when the second fixture 54 is moved away from the first fixture 52, the protrusion 64 of the second fixture 54 abuts against the rotation preventing member 56, and the second fixture Further movement of the tool 54 is prevented. Therefore, in the present embodiment, the rotation preventing member 56 and the protruding portion 64 are movement restricting means for restricting the amount of movement of the second fixing tool 54 relative to the first fixing tool 52, and the first fixing tool. It is also a retaining means for preventing 52 from falling off the second fixture 54. And this rotation prevention member 56 and the protrusion part 64 function also as a temporary fixing means which temporarily fixes the position of both when inserting the volt | bolt 53 in the 1st fixing tool 52 and the 2nd fixing tool 54. FIG.

Next, with the first fixing member 52 and the second fixing member 54 temporarily fixed, the bolts 53 are inserted into the bolt holes 58 of the first fixing member 52 and the bolt holes 62 of the second fixing member 54. Then, the nut 65 is screwed and tightened. At this time, similarly to the first embodiment, the bolt 53 may be held with a spanner, and the outer surface of the first fixture 52 may be held with another spanner.
As the bolt 53 is tightened, the second fixing member 54 tries to rotate about the width direction axis passing through the front end and the lower end of the second fixing member 54, but the rotation preventing member 56 is the second fixing member 54. The second fixture 54 is prevented from rotating by contacting the upper surface of the fixture 54. Further, the second fixing tool 54 is prevented from rotating by the bottom surface of the second fixing tool 54 coming into contact with the bottom surface of the first fixing tool 52. On the other hand, the first fixing member 52 is prevented from rotating by the rotation preventing member 56 coming into contact with the upper surface of the second fixing member 54. Here, the position of the rotation preventing member 56 is set so as to abut on or directly above a portion other than the protruding portion 64 on the upper surface of the second fixture 54. The rattling of the first fixture 52 and the second fixture 54 is almost eliminated.

According to the second embodiment having the above-described structure, the same effects as those obtained in the first embodiment can be obtained, and the following effects can be obtained.
The anti-rotation means includes an anti-rotation member 56, a hole 60 of the first fixture 52, and a nut 66. The rotation prevention means rotates the first fixture 52 and the second fixture 54. Can be prevented. Therefore, since the first fixing tool 52 and the second fixing tool 54 can be formed into a simple structure such as a U-shaped member having an open top surface, the fixing structure can be easily manufactured.

  The distal end portion of the second fixture 54 is inserted into the first fixture 52, and the second fixture 54 is fixed in a state where the first fixture 52 and the second fixture 54 are fixed to each other. The bottom surface is in contact with the bottom surface of the first fixture 52. Accordingly, when the bolt 53 is tightened, the second fixing tool 54 can be prevented from rotating by the bottom surface of the second fixing tool 54 coming into contact with the bottom surface of the first fixing tool 52. Further, since the lower end of the distal end portion of the second fixture 54 abuts on the bottom surface of the first fixture 52, a large local stress is applied to the fuel tank 100 by the corner portion of the second fixture 54. Therefore, damage to the fuel tank 100 can be prevented. This eliminates the need to install a rubber plate-like member between the fuel tank 100 and the fixing structure of the fixing band 50.

  The rotation preventing member 56 abuts against the protrusion 64 of the second fixture 54, so that the second fixture 54 can be prevented from falling off the first fixture 52. Therefore, the first fixing member 52 and the second fixing member 54 can be temporarily fixed when the bolt 53 is inserted, and the fixing operation can be easily performed. This is because when the fixing band 50 is made of metal, the bolt 53 is inserted into the first fixing member 52 and the second fixing member 54 even if the fixing band 50 is bent along the periphery of the fuel tank 100. In particular, it is possible to prevent the fixed band 50 from bouncing back, which is particularly advantageous.

The present invention is not limited to the above-described embodiment. For example, the rotation preventing means includes the form of the upper surface portion 18 as in the first embodiment and the rotation preventing member 56 as in the second embodiment. For example, the structure may be such that the pins are fixed to each other with pins penetrating both in the width direction or the height direction so that the rotational movement of both is restricted. Further, the rotation preventing means does not contact the upper surface of the second fixture, for example, the first fixture has a member that penetrates in the longitudinal direction of the second fixture, so that the other You may suppress the rotation around the width direction axis line of a fixing tool. In this case, the penetrating member is brought into contact with the second fixing tool at a position closer to the base end side of the second fixing tool than the support position of the bolt of the second fixing tool.
In the present invention, as a configuration of the rotation preventing means that contacts the upper surface of the second fixing tool, in addition to a structure that directly contacts the upper surface of the second fixing tool, for example, on the upper surface of the second fixing tool, A structure that abuts via a protrusion is also included.

The bolts are not limited to being supported at two points by the first fixing tool and the second fixing tool, but may be supported at three or more points, respectively, and the first fixing tool and the second fixing tool. The number of support positions for supporting the bolts may be different. It is sufficient that at least one bolt hole is provided. For example, other bolts may not be supported by the bolt hole. For example, the concave portion that supports only the lower surface side of the bolt or the upper surface side of the bolt is supported. It may be a recess.
In addition, in the above-described embodiment, the nut and the bolt are arranged in such a manner that the nut is welded to the second fixing tool and the bolt is inserted from the first fixing tool side. A structure in which the bolt is inserted from the second fixture side may be used.

The fixed band is not limited to being divided into two, and may be composed of one. What is necessary is just to attach a 1st fixing tool and a 2nd fixing tool to the edge part which opposes, when attaching a fuel tank. Further, the fixing band is not limited to a metal one, and can be made of any material. Furthermore, any number of fixing structures can be provided on the fixing band.
In addition, the fixing band is not limited to the one that fixes the fuel tank disposed in the oil guard as in the above-described embodiment, and can be similarly applied to a fuel tank that is not housed in the oil guard.
The first fixing tool and the second fixing tool are not limited to a substantially rectangular parallelepiped shape having a rectangular cross section, and may have a polygonal cross-sectional shape such as a hexagonal shape or an octagonal shape. As long as it is reliably positioned with respect to the tank, it is not limited to a polygon but may be a circle.

  In the above-described embodiment, the first fixing device surrounds the second fixing device from three sides of the upper surface and both side surfaces in the first embodiment, and in the second embodiment, the first fixing device includes the lower surface and both side surfaces. However, the present invention is not limited to this. For example, the rotation preventing means has a cylindrical portion formed on the first fixture, and the first fixture and the second fixture are bolts. In the state of being fixed to each other, at least a part of the second fixing tool may be inserted into the cylindrical portion of the first fixing tool. In such a structure, the first fixture surrounds the second fixture from four directions.
