At this time, by fitting the first flange portion 28 and the second flange portion 78 into the pair of holes 88, 88, the separation of the first flange portion 28 and the second flange portion 78 from each other is regulated, and as a result, The separation of the second connecting portion 16 and the first holder 70 from each other is restricted. That is, the state where the first holding member 70 is screwed to the second connection portion 16 is held. Thereby, the connected state where the first gas pipe 10 and the second gas pipe 40 are connected is maintained.

  In the above-described connection state, the third connection portion 46 is rotatable about the rotation axis AX with respect to the second connection portion 16. That is, the shaft portion 42A that is coaxial with the third connection portion 46 is rotatable about the rotation axis AX with respect to the second connection portion 16. Therefore, the second gas pipe 40 is rotatably supported on the second connecting portion 16 around the axis of the shaft portion 42A. Further, since the fourth connection portion 44 (tip) of the second gas pipe 40 is disposed at a position shifted from the rotation axis AX, when the second gas pipe 40 rotates with respect to the first gas pipe 10, The position of the fourth connection portion 44 (tip portion) of the second gas pipe 40 is changed.

Subsequently, a usage example of the above-described gas pipe unit 1 will be described.
Here, when the gas stove 90 and the second gas appliance (not shown) are incorporated in the cabinet 96, more specifically, the gas stove 90 is incorporated in the upper part of the cabinet 96, and the gas stove 90 is sandwiched by the partition plate 97. The case where the second gas appliance is arranged below (immediately below) is described.

  As shown in FIGS. 4 and 5, a through-hole 98 that penetrates vertically is formed at a position near the rear end on the right side of the partition plate portion 97. In a region below the partition plate portion 97, a gas pipe (not shown) extending from the second gas appliance is fixed to the lower surface of the partition plate portion 97 such that a gas flow path inside the gas pipe and the through hole 98 communicate with each other. You. In the region above the partition plate portion 97, one end of the third gas pipe 94 is fixed to the upper surface of the partition plate portion 97 so that the gas flow path inside the third gas pipe 94 and the through hole 98 communicate with each other. The third gas pipe 94 is, for example, a flexible pipe having flexibility, and the other end is connected to the distal end portion (the fourth connection section 44) of the gas pipe unit 1. That is, the connection part 95 that constitutes the other end of the third gas pipe 94 corresponds to the external connection part on the second gas appliance side. When the connecting portion 95 of the third gas pipe 94 is connected to the distal end (fourth connecting section 44) of the second gas pipe 40 (gas pipe unit 1), the gas flow path on the third gas pipe 94 side and the second The gas flow path on the gas pipe 40 (gas pipe unit 1) side communicates with the gas flow path.

  FIGS. 4 and 5 show a state in which a member above the connection part 91 is removed from the gas stove 90 so that the connection state between the connection part 91 of the gas stove 90 and the gas pipe unit 1 can be easily understood.

  A first gas stove 90A shown in FIG. 4 and a second gas stove 90B shown in FIG. 5 both have a connection portion 91 arranged at a position near the rear end on the left side, and a back plate constituting a back portion of the gas stove 90. The second embodiment is common in that it has a portion 92 and that a through hole 93 penetrating in the front-rear direction is formed at the left end of the back plate 92. However, the first gas stove 90A and the second gas stove 90B are different from each other in the direction of the connection port of the connection portion 91. Specifically, in the first gas stove 90A shown in FIG. 4, the direction of the connection port of the connecting portion 91A is directly behind the first gas stove 90A. On the other hand, in the second gas stove 90B shown in FIG. 5, the direction of the connection port of the connection portion 91B is inclined leftward (in a direction away from the through-hole 98) with respect to the position directly behind.

  As shown in FIG. 4, when the gas pipe unit 1 connects the first gas stove 90 </ b> A and the connection portion 95, first, the first connection portion 14 is formed through the through hole formed on the back plate portion 92 </ b> A of the first gas stove 90 </ b> A. The first gas stove 90A is inserted through the hole 93A into the first gas stove 90A, and is connected to the connection portion 91A of the first gas stove 90A. Then, the gas pipe unit 1 has its distal end directed toward the connection part 95 side. At this time, the first pipe portion 12 of the gas pipe unit 1 extends right behind the connection portion 91A of the first gas stove 90A, and bends toward a position slightly forward of the connection portion 95. In this state, when the second gas pipe 40 is rotated with respect to the first gas pipe 10 so that the tip end (fourth connection portion 44) of the second gas pipe 40 faces obliquely rearward, the second gas pipe 40 The tip has a form in which the tip (fourth connection part 44) extends toward the connection part 95, and the tip part (fourth connection part 44) of the second gas pipe 40 is arranged near the connection part 95. For this reason, the user can bend the third gas pipe 94 to connect the distal end portion (the fourth connection section 44) of the second gas pipe 40 and the connection section 95.

  On the other hand, when the gas pipe unit 1 connects the second gas stove 90B and the connection portion 95 shown in FIG. 5, the first connection portion 14 is first formed on the back plate portion 92B of the second gas stove 90B. It is inserted into the second gas stove 90B through the through hole 93B, and is connected to the connection portion 91B of the second gas stove 90B. Then, the gas pipe unit 1 has its distal end directed toward the connection part 95 side. At this time, the first pipe portion 12 of the gas pipe unit 1 extends rightward from the connection portion 91B of the second gas stove 90B toward the left (toward the direction away from the connection portion 95), and is bent to connect the connection portion 95. It extends to a position slightly behind. In this state, when the second gas pipe 40 is rotated with respect to the first gas pipe 10 so that the distal end (the fourth connection portion 44) of the second gas pipe 40 faces obliquely forward, the second gas pipe 40 The tip has a form in which the tip (fourth connection part 44) extends toward the connection part 95, and the tip part (fourth connection part 44) of the second gas pipe 40 is arranged near the connection part 95. For this reason, the user can bend the third gas pipe 94 to connect the distal end portion (the fourth connection section 44) of the second gas pipe 40 and the connection section 95.

Next, main effects of the present configuration will be exemplified.
In the gas pipe unit 1, the first gas pipe 10 has a first connection portion 14 connected to a connection portion 91 (external connection portion on the gas stove side) on one end side, and a second connection portion 16 on the other end side. And constitutes a flow passage communicating with the connection portion 91 (external connection portion on the gas stove side). And the 2nd gas pipe 40 has the 3rd connection part 46 connected to the 2nd connection part 16 of the 1st gas pipe 10 in one end side, and the connection part 95 (external connection part by the side of the 2nd gas appliance). The other end has a fourth connection portion 44 that is connected to the first gas pipe 10 and a connection portion 95 (an external connection portion on the side of the second gas appliance). The second gas pipe 40 is rotatably connected to the first gas pipe 10 about a predetermined rotation axis AX, and the fourth connection portion 44 is disposed at a position shifted from the rotation axis AX. It is free to rotate around AX. With such a configuration, the user can make an adjustment so as to rotate the second gas pipe 40 to displace the fourth connection portion 44 around the rotation axis AX. Therefore, even if the position and the direction of the external connection part on the gas stove side are different (that is, even if the position and the connection direction to which the first gas pipe 10 is connected are different), the fourth connection part of the second gas pipe 40 is different. 44 can be adjusted so as to approach a desired position (near the external connection portion on the second gas appliance side), and the fourth connection portion 44 can be easily connected to the external connection portion on the second gas appliance side.

  Further, the second gas pipe 40 extends along the direction of the rotation axis AX, and is bent from the other end of the shaft portion 42A with the third connection portion 46 provided at one end side, and is bent at the other end of the shaft portion 42A. An extending part 42B extending along a predetermined direction inclined with respect to the direction, and having a fourth connecting part 44 provided on the opposite side to the shaft part 42A. According to this configuration, the simple configuration of providing the extending portion 42B that bends from the other end of the shaft portion 42A provides “the fourth connection portion 44 is disposed at a position shifted from the rotation axis AX, and is arranged around the rotation axis AX. It is possible to realize a "rotatable" configuration. Therefore, “a configuration that is applicable even if the positional relationship between the external connection portion on the gas stove side and the external connection portion on the second gas appliance side is different” can be realized in a form in which the shape is not complicated.
