Abstract
PURPOSE: To fix a shape member and a rod member to each other by crushing their ends, and improve joining strength by inserting the shape member to the stepped rod member of which the leading end is smaller in section that a rod body and compressing the leading end in the axial direction.
CONSTITUTION: A small-diameter rod part 12b of a section smaller than the section of a rod body 12a of a diameter equal to that of a desired core rod is formed to one end in the axial direction of the rod body 12a. On the other hand, the outside circumference 11a of a shape member 11 consisting of an abrasion resistant material is formed to the same diameter as that of the rod body 12a, and a through-hole 11b fitting to the part 12b is formed to the central stem part of the member 11. Thence, the member 11 is upset hot to the part 12b to crush a leading end part 12c to a disc shape, thereby forming a fixing part 12d are forming the member 11 and the member 12 into one body.
