First, the pipe 1a having the protrusion 6 in a part of the pipe is inserted into the hole 21 of the base 2b (the same applies to the case of 2a) until it reaches a fixed position, that is, until the protrusion 6 comes into contact with the outer surface of the base. And the outer periphery is attached by brazing or the like. Next, the pipe 1b is inserted into the holes 22 and 23 of the base 2b in the same manner as described above, and welded by brazing or the like. At this time, the pipe 1b does not have the projection 6, but when it is inserted into the pipe insertion hole of the base 2b, it comes into contact with the tip of the pipe 1a near the inner surface of the base and is not inserted more than necessary into the inside of the base, so that the position is securely determined. It is.
