Gear for transmission and method for manufacturing the same

摘要

A method for manufacturing a gear (10) and a gear (10) for a transmission, in which an outer peripheral gear part formed on an outer peripheral wall surface of a main body of a gear (10), an annularly-shaped concave portion (12) annularly formed at a radial inner part on at least one axial end surface of the main body of the gear (10) within the outer peripheral gear part thereof, a dog gear part (13) formed on an outside peripheral wall surface (12) at a central part (15) formed on the annularly-shaped concave portion (12), and a taper part comprising an inner corn for synchro formed on an inside peripheral wall surface (121) formed on the annularly-shaped concave portion (12), are formed integrally by forging.
