According to one embodiment of the present invention, a drive shaft for a vehicle, comprising: a shaft unit formed in a predetermined length and having a groove sunken towards the inside in one point on an outer circumferential surface, wherein adhesives are coated in the groove; and a vibration damping member pressed and inserted into one side of the shaft unit to be arranged on the outer circumferential surface, having the groove, of the shaft unit, and adhering the adhesives on an inner surface which makes close contact with the outer circumferential surface of the shaft unit, so as to be fixed in the shaft unit when being pressed and inserted. According to the present invention, a screw type groove is formed on the outer circumferential surface of the shaft unit and capsule type adhesives pressed and torn by the inner surface of the pressed/inserted vibration damping member are coated on the groove, so the vibration damping member is completely fixed in the shaft unit, and thereby stably absorbing vibration and noises without coming out from a set position even when a composite vibration cause occurs. Therefore, durability and mileage of the vehicle are improved.

    본 발명의 한 실시예에 따른 자동차용 드라이브 샤프트는 미리 설정된 길이로 형성되어, 외주면의 어느 한 지점에 내측을 향하여 함몰된 홈이 형성되고, 상기 홈에는 접착제가 도포되는 샤프트부, 그리고 상기 샤프트부의 일측으로 압입되어 상기 홈이 형성된 상기 샤프트부의 외주면에 배치되고, 압입 시 상기 샤프트부의 외주면에 밀착되는 내면에 상기 접착제가 접착되어 상기 샤프트부에 고정되는 진동감쇠부재를 포함한다. 본 발명에 의하면, 샤프트부의 외주면에 나선형의 홈을 형성하고, 홈에는 압입 중인 진동감쇠부재의 내면에 가압되어 터지는 캡슐형 접착제를 도포함으로써, 진동감쇠부재는 샤프트부에 완전히 고정되며, 이를 통해 복합적인 진동 요인이 발생될 경우에도 설정위치를 이탈하지 않고, 안정적으로 진동 및 소음을 흡수하여 차량의 내구성 및 연비를 향상시킬 수 있다.
