Abstract
A method of manufacturing a tooth-shaped component including a process of draw-forming a workpiece so as to obtain a cylindrical container, which has a bottom surface portion and a side surface portion; a diameter-reducing process of reducing the diameter of a particular part in which a tooth tip portion is to be formed in the side surface portion of the cylindrical container, so as to increase the thickness of a corner portion such that an external shape of the corner portion between the bottom surface portion and the side surface portion satisfies the following conditional expression (ΔR+ΔH)≤2t; and a tooth shape-forming process of forming the tooth tip portion in the particular part of the cylindrical container reduced in diameter in the diameter-reducing process, so as to obtain a tooth-shaped component which has the bottom surface portion, the side surface portion, and the tooth tip portion.
