ができなかつた。Problems that the invention attempts to solve However, in the above radiator tank,
Since the tip semicircular portion 6 of the pipe 5 is brazed and fixed to the inner wall surface of the tank body 1 via the support 7, the mounting structure of the pipe 5 is accordingly complicated. In addition, the pipe 5 is supported and fixed by brazing at the insertion part into the mounting hole 3 and the tip semicircular part 6, but since one end is the tip semicircular part 6 with a cutout at the top, brazing is not possible. The fixed area was small and sufficient support strength could not be obtained, and as a result, the pipe 5 vibrated greatly due to engine vibrations, etc., causing cracks in the brazed parts where stress was concentrated, resulting in leakage of coolant. Moreover, since the pipe tip 4 of the pipe 5 has a semicircular shape with a cutout, the cooling liquid flows out at once from the large opening, resulting in uneven flow as shown in FIG. The coolant did not flow uniformly, and the radiator was unable to perform its full function.
