PROBLEM TO BE SOLVED: To provide a method for manufacturing a transmission gear which can reliably identify and control similar transmission gears in manufacturing processes.SOLUTION: A method for manufacturing a transmission gear mainly includes: a molding step of molding with a material (A) to form a molded material (B) of a transmission gear (C5s); and a cutting step of cutting the molded material (B) to form the transmission gear (C5s). In the molding step, an identifying mark (D) is formed at a cutting allowance part (p) to be cut-out in the cutting step. |
