Abstract
A method for manufacturing a fuel inlet having a good sealing property and a screw structure formed in a precise position involves expanding one end of a long-length stainless pipe (metal pipe) using a cored bar, the tip of the expanded portion which becomes non-uniform as a result of the expanding step is cut off, a screw structure is formed in the expanded portion by using a punch, the tip of the expanded portion which becomes non-uniform as a result of the screw structure forming step is cut off, and thereafter curl forming is conducted to the end of the expanded portion which becomes uniform by using a die so as to provide a seal portion.
