Abstract
PURPOSE:To simplify the working process, and also, to improve the yield of a product by working a pipe member in which plural cross-shaped notches have been formed, so that the notch parts are spread out to the outside, by press working. CONSTITUTION:At the end part of a pipe member 1, cross-shaped notches 3, 4, 5 and 6 are formed. Subsequently, the pipe member 1 on which such pre- working has been executed, press working is performed, and the notch parts 3, 4, 5 and 6 are pushed and spread out to the outside. On a flange part which has been formed in such a way, a fitting hole 8 is pierced. According to this method, the manufacturing process can be simplified, and also, the product yield is improved.
