According to the method of the invention, a worm portion is formed at a worm forming portion by a rolling process with rolling dies, and a small diameter portion is formed at least at one axial end of the worm forming portion, wherein a diameter of the small diameter portion is smaller than a diameter of a bottom of a worm tooth to be formed at the worm forming portion, so that surplus material portion of the worm forming portion can flow toward the small diameter portion.
