Zusammenfassung:	The present invention relates to a method for manufacturing a pinion gear using a cold forging method. The method according to the present invention can reduce manpower consumption and shorten manufacturing time compared to a production method consisting of only a multi-step press process, thereby maximizing productivity and improving working environments, and also does not need a separate mechanical cutting process for an external gear part, thereby reducing additional cost and improving dimensional accuracy and mechanical properties. 본 발명은 냉간단조공법을 이용하여 피니언 기어를 제조하는 방법에 관한 것으로, 본 발명에 따르면 다단계의 프레스 공정으로만 이루어지는 생산방식에 비하여 인력소모를 줄이고 제작시간을 단축할 수 있어 생산성의 극대화 및 작업환경을 개선할 수 있을 뿐만 아니라, 외경기어부에 대해 별도의 기계적 절삭가공이 불필요하므로 추가 비용을 절감할 수 있고 치수 정밀도와 기계적 성질을 향상할 수 있는 효과가 있다.
