摘要： According to a fabrication method, an extruded tubular member HA is formed, using an extrusion die 23 which has an extrusion orifice 25 having an opening-side inner circumferential surface 25a having a circular section and a core-side die 26 disposed concentrically with the extrusion orifice 25, by extruding a tube material through an extrusion passage 27 defined between the opening-side inner circumferential surface 25 and a core-side outer circumferential surface 26d of the core-side die 26. As this occurs, a bent configuration is given to the extruded tubular member HA by changing contact areas where the tube material contacts the opening-side inner circumferential surface 25a and the core-side outer circumferential surface 26d in a circumferential direction so as to set velocities at which the tube material is extruded to different values in the circumferential direction by controlling the position of the core die 26 in rotating and axial directions relative to the extrusion orifice 25.
