<p>PURPOSE:To perform the use of a common flange member despite of the bending angle of a pipe by a method wherein a clamp piece and a flange body are fastened against each other by means of a fixing means in a state that a pipe is nipped between the arcuate recessed part of the clamp piece and the pipe holding recessed part of the flange body. CONSTITUTION:A clamp piece 22 is brought into an opened state and a pipe 23 is inserted in an opening part 25 from the direction of a side and fitted in a pipe holding recessed part 26. In this case, by utilizing the bead part 61 of the pipe 23, positioning in an axial direction of a flange part 20 is carried out. The clamp piece 22 is closed and a flange body 21 and the clamp piece 22 are fastened against each other by means of a caulking part 53. The flange member 20 is fixed to a device 31 on the mating side by means of a bolt 32. Further, the end part of the pipe 23 is inserted in a connection hole 65 formed in the device 31 on the mating side and sealed by means of a sealant 62. This constitution causes the use of the common flange member 20 even when the bending angle of the pipe is changed.</p> |
