Abstract
In a machining tool, multiple tooth forming portions for plastically forming spline teeth on an axial end face of a vehicle hub unit, the axial end face facing inward in the vehicle lateral direction, are formed in a circular pattern about the central axis of the machining tool. In the machining tool, a rounded-portion forming portion is formed to form a rounded portion between a tooth flank and a top land of each spline tooth, and the radius of the rounded-portion forming portion gradually changes in the radial direction about the central axis.
