A bushing is then forced through the opening in a bushing driving direction such that the bushing engages the annular edge portion and deforms the annular edge portion in the bushing driving direction to form an annular flange portion on the metal member which projects in the driving direction and engages an exterior surface of the bushing in an interference fit relation so as to securely retain the bushing within the opening.
