Abstract

A flanged housing member is formed using a forming method and a forming device from a forming material having a pre-flanged forming portionis disposed at one end of a trunk portion. The entire external surface of the flanged housing member can be ironed with a sufficient degree of precision without mechanical machining. The forming material is held on one of a first die having an external forming surface and a second die having an internal forming surface. A sizing process is performed to at least form an internal surface of the trunk portion using the first and second dies. The pre-flanged forming portion is sandwiched and pressed between the first die and a flange-forming die to form a flange portion on the end of the trunk portion.
