Each of the pipe fixing portions 5 includes a pair of long holes 9. Each of the long holes 9 is formed in a rectangular shape having a planar shape and a corner having an arc shape. The pair of long holes 9 are arranged at intervals from each other along the width direction (direction orthogonal to the longitudinal direction) of the flat plate portion 4. The pair of long holes 9 are arranged such that the longitudinal direction thereof is parallel to the width direction of the flat plate portion 4. Further, in the illustrated example, the pipe fixing portion 5 is disposed at a position where a line segment P (indicated by a one-dot chain line in FIG. 3) passing through the center between the pair of long holes 9 is parallel to the longitudinal direction of the flat plate portion 4. Has been.

  As shown in FIG. 4, the U-bolt 6 is formed in a U-shape when viewed from the side, and thread grooves are formed on the outer peripheral surfaces of both ends. The U-bolt 6 is passed through the pipe 3 on the inside and both ends are passed through the long hole 9. The U-shaped bolt 6 has a nut 10 as a fastening member screwed (fastened) to both ends thereof, and the flat plate portion 4 and the pipe 3 are sandwiched between the nut 10 and the flat plate portion of the pipe 3. 4 That is, the fixture 1 is fixed.

  The device fixing portion 7 is provided at the center of the flat plate portion 4 and includes a pair of burrings 11. As shown in FIG. 5, the pair of burrings 11 are arranged at intervals from each other along the longitudinal direction of the flat plate portion 4. The burring 11 is formed in a cylindrical shape penetrating the inside and standing from the flat plate portion 4 toward the pipe 3. Further, the burring 11 has a thread groove formed on its inner peripheral surface, and the screw 12 and the like are screwed together. The device fixing portion 7 is a mounting piece between the head of the screw 12 and the flat plate portion 4 by the screw 12 passing through the through hole 2b (shown in FIG. 5) of the mounting piece 2a of the gas meter controller 2 being screwed. The gas meter controller 2 is fixed to the flat plate portion 4, that is, the fixture 1 by sandwiching 2 a. Moreover, each burring 11 of the apparatus fixing | fixed part 7 is arrange | positioned in the position spaced apart from the line segment P mentioned above.

  The electric wire fixing portion 8 includes round holes 13 provided at each corner of the flat plate portion 4. That is, the wire fixing portion 8 includes four round holes 13. Of course, the round hole 13 penetrates the flat plate portion 4. The electric wire fixing part 8 passes the band 15 (shown in FIG. 1) wound around the electric wire 14 connected to the gas meter controller 2 inside, and the electric wire 14 is fixed by the band being tied. Since the round hole 13 is provided in the corner of the flat plate portion 4, the electric wire fixing portion 8 routes (wires) the electric wire 14 along the outer edge portion of the flat plate portion 4.

  The above-described fixture 1 has both ends of the U-shaped bolt 6 through which the pipe 3 is passed through the inside of the long hole 9, and nuts 10 are screwed into both ends of the U-shaped bolt 6, so that the flat plate portion 4 Is attached to the pipe 3. Then, the screw 12 is passed through the through hole 2 b of the mounting piece 2 a of the gas meter controller 2, and the screw 12 is screwed into the burring 11, thereby attaching the gas meter controller 2 to the flat plate portion 4. Then, the band 15 wound around the electric wire 14 is passed through the round hole 13 and attached to the outer edge portion of the flat plate portion 4. Thus, the fixture 1 having the above-described configuration attaches the gas meter controller 2 to the pipe 3.

  According to this embodiment, since the flat plate portion 4 is formed in a rectangular flat plate shape, the shape of the flat plate portion 4, that is, the fixture 1 can be simplified. Therefore, it is possible to prevent an increase in the number of steps and processes for manufacturing the fixture 1, and it is possible to reduce the cost.

  Moreover, since the pipe fixing part 5 includes a pair of long holes 9 whose longitudinal direction is parallel to the width direction of the flat plate part 4 and spaced in the width direction, both ends of the U-shaped bolt 6 are long holes. By appropriately changing the position passing through the inside 9, the fixture 1 can be attached to the pipe 3 having various outer diameters.

  Furthermore, since the pipe fixing portions 5 are provided at both ends in the longitudinal direction of the flat plate portion 4, the flat plate portion 4 can be attached to the pipe without wobbling with respect to the pipe 3. Therefore, the gas meter controller 2 can be securely attached to the pipe 3.

  Since the device fixing portion 7 is disposed at a distance from the line segment P passing through the center between the pair of long holes 9 of the pipe fixing portion 5, the gas meter controller 2 is attached to the flat plate portion 4 without interfering with the pipe 3. Can be attached.

  Since the device fixing portion 7 includes the cylindrical burring 11, it is not necessary to make the shape of the device fixing portion 7 complicated. Therefore, the cost of the fixture 1 can be further reduced.

  Since the round hole 13 of the electric wire fixing portion 8 is provided at the corner of the flat plate portion 4, the electric wire 14 connected to the gas meter controller 2 is fixed to the flat plate portion 4 without interfering with the pipe fixing portion 5 and the device fixing portion 7. be able to.
