<p>PROBLEM TO BE SOLVED: To provide a forging molding gear capable of reducing a molding load during forging, and easily determining existence/absence of generation of underfill of a tooth flank.SOLUTION: In a bevel gear in which a plurality of teeth 20 are formed by being pressed by an upper die and a lower die, a plurality of R-shaped projection parts 30 are formed, which rise from each tooth tip part 23 and extend to the inside of each tooth as a face adjacent to each tooth flank 22 approaches the outside in the radial direction. Thereby, a quality guarantee shape capable of viewing each tooth tip part 23 is imparted to each tooth tip part 23 of each tooth.</p> |
