Abstract

PURPOSE:To provide an inexpensive metal fitting which is excellent in the durability and reliability by forming a small bottomed hole for caulking in a flange from the periphery of a hole in the flange, into which a nipple is to be inserted, toward the hole, and allowing the bottomed part of the small hole to project toward the nipple after the nipple is inserted into the flange. CONSTITUTION:A small bottomed hole 19 is drilled by a drill, etc., at a symmetrical position of an aluminum alloy flange 12 toward a hole 18, into which an aluminum alloy made nipple 11 is to be inserted. After the nipple 11 is inserted into the hole 18, a punch is pressed into the bottomed hole 19 to allow the bottomed part of the bottomed hole 19 to project to deform 20 the hole 18 inwardly. Thus, the periphery of the nipple 11 is caulked to fix the nipple 11 to the flange 12 integrally. When the bottomed hole 19 is formed at a symmetrical position of the flange 12, the pressing position of the punch is always stable, a point 21 is positively caulked, and a drawback in that the punch deviates from the point to damage the appearance, is eliminated. Thus, a metal fitting which eliminates the need for rust preventive processing and which is excellent in durability can be obtained.
