Patent abstract
In making a component part of a reclining device that is used to adjust an inclination of a seat back with respect to a seat cushion, after the component part has been prepared, a predetermined portion of the component part is selectively heated up to a temperature greater than a transformation point of a material of the component part, and the component part is then cooled. During this heat treatment, portions of the component part other than the predetermined portion are left as a base material to thereby selectively increase the strength or the wear and abrasion resistance of the component part.
