A current is passed between 0 and 24. Then, the end of the flange 16 is welded to the flat portion 8 by the resistance heat, and the flange 16 is gradually expanded by pressurization, and the expanded portion is further welded. In this way, the entire circumference of the flange 16 is finally welded to the flat portion 8. When the breather tube 4 is brazed, the heat-affected zone is large, but by using projection welding, the heat-affected zone can be reduced, and rust prevention performance can be improved.
