A method of producing a bevel gear is provided. The method comprises the steps of forging, from a case hardened and heated blank, a rough shaped bevel gear intermediate product having a toothed portion, outer burrs at a larger diameter end thereof and between adjacent teeth of the toothed portion, and a ring-shaped inner burr in a center hole thereof, setting the rough shaped bevel gear intermediate product in a trimming die during the time the rough shaped bevel gear intermediate product remains in an elevated temperature condition due to heat left therein after the step of forging, and trimming the outer burrs, and moving, after the step of trimming, the rough shaped bevel gear intermediate product from the trimming die to a sizing die in the vicinity of the trimming die and warm sizing the toothed portion in succession to the step of trimming.
