Abstract
In a method for manufacturing a burring processed member, an inner-circumferential surface of a plate-like curved portion is pressed in a first direction, thereby forming a side wall and a seating face, the side wall protruding from a rim of a first hole, the seating face extending from a tip of the side wall. In the method, a circular second hole is formed on the seating face, and the burring processed portion protruding in the first direction from the rim of the first hole is formed. The seating face includes two crests, each situated on a periphery of each end of the curved portion in a circumferential direction, and is slanted such that a seating face height becomes smaller from each of the crests to a substantial center in the circumferential direction.
