継手。 A short cylindrical body for fitting a branch pipe having a pair of diametrically opposed concentric through holes on both sides, and a peripheral wall that penetrates this short cylindrical body through both of the through holes, and a branch hole that opens into the short cylindrical body. In a branch pipe joint having a main pipe in the area and a brazing means for joining the peripheral edge of each through hole of the short cylinder to the outer circumferential wall of the main pipe, the portion of the main pipe in the area between both the through holes of the short cylinder is It is formed as an enlarged diameter part that bulges outward in the radial direction by plastic deformation and presses closely against the periphery of both through holes in the short cylindrical body, and the main pipe is brazed to the periphery of both through holes in the short cylindrical body in this enlarged diameter part. A branch pipe joint characterized by:
