Abstract
An engaging dented portion is formed in a region from an axially intermediate portion of the pipe insertion hole to a position of a connecting surface of a flange on an inner peripheral surface of the pipe insertion hole. The end portion of the pipe is inserted into the pipe insertion hole of the flange so that the end face of the pipe is positioned within a range from the axially intermediate portion of the pipe insertion hole to a position of the connecting surface of the flange. Next, each die segment of an expanding die arranged in the hollow portion of the pipe is moved radially outward of the pipe to thereby subject the end portion of the pipe to an expanding process so that the end portion of the pipe is engaged with the engaging dented portion. With this, the flange is connected to the end portion of the pipe.
