く、仕切り部３３がなくても良いことは勿論である。In the fitting portion 45A, a pair of tip portions 491a is formed on a side surface portion 491b of the fitting concave portion 49A, and these tip portions 491a are formed on one side edge 41 side of the pipe main body 31. Since each is bent toward 51A, the one side edge 41 and the other side edge 43 can be more firmly connected. In the embodiment described above, an example in which the partition 33 is formed in the pipe main body 31 has been described. However, the present invention is not limited to this embodiment, and the partition 33 may be omitted. It is.

In the header pipe, the width in the axial direction of the side surface of the fitting recess is made larger than the width in the axial direction of the tip,
Since both edges of the distal end are formed at positions away from both edges of the side surface, the distal end can be easily and reliably bent into a predetermined shape. In the header pipe for a heat exchanger of the second aspect, a plurality of tips are formed on the side face of the fitting recess at intervals in the axial direction, and these tips are formed on one side of the pipe body. Since each of the bent portions is bent toward the concave portion, the one side edge portion and the other side edge portion can be more firmly connected.
