Abstract
A method for manufacturing a gear, wherein the gear is formed on a forging process by a die having an inner peripheral surface. A plurality of top surfaces corresponding to a bottom surface of the gear and both projected side surfaces corresponding to tooth surfaces of the gear and sandwiching the top surface connect smoothly to each other. The tooth surfaces and the bottom surface of the formed gear connect to each other smoothly. The forging process is carried out as a hot forging process in which the gear is formed by a hot forging die, or the forging process is carried out as a cold forging process in which the gear is formed by a cold forging die.
