Zusammenfassung:	The present invention relates to a drive shaft assay for a vehicle and a manufacturing method thereof and, more particularly, to a shaft and an inner ring. The present invention may include a solid shaft and an inner ring integrally formed with the solid shaft, and a manufacturing method thereof may comprise the steps of: forging a solid shaft to form an inner ring; processing the solid shaft and inner ring; and performing high-frequency heat treatment on the processed solid shaft and inner ring. According to the present invention, the outer diameter of the inner and outer rings is reduced by integrating the shaft and the inner ring, so that the weight of the drive shaft assay can be reduced by 10 to 20%. In addition, the cost of manufacturing and managing parts can be reduced by omitting spline processing and deleting a circlip. 본 발명은 자동차용 드라이브샤프트 앗세이 및 이의 제조방법에 관한 발명으로 보다 구체적으로 샤프트 및 내륜에 관한 발명이다. 본 발명은 중실 샤프트 및 중실 샤프트와 일체로 형성된 내륜을 포함할 수 있으며 그 제조방법은 중실 샤프트를 단조하여 내륜을 형성하는 단계, 중실 샤프트 및 내륜을 가공하는 단계 및 가공된 중실 샤프트 및 내륜을 고주파 열처리하는 단계를 포함할 수 있다. 본 발명은 샤프트 및 내륜을 일체화함으로써 내륜 및 외륜의 외경이 감소되어 드라이브 샤프트 앗세이의 중량이 10~20% 절감될 수 있다. 또한, 스플라인 가공 생략 및 써클립의 삭제로 부품 제작 및 관리 비용이 감소시킬 수 있다.
