The present invention relates to a strut bar for a vehicle, which comprises a body (120) which has a double pipe structure including an inner pipe (122) and an outer pipe (126). On the outer circumferential surface of the inner pipe (122), a plurality of protrusions (124) are formed in a longitudinal direction. On the inner circumferential surface of the inner pipe (122), line grooves (128) corresponding to the protrusions (124) are formed. As the protrusions (124) are accommodated in the line grooves (128), the inner pipe (122) is inserted to and engaged with the outer pipe (126), thereby increasing the torsion rigidity. The line grooves (128) are formed in a number which is at least twice the number of the protrusions (124). In a process of inserting the inner pipe (122) to the outer pipe (126), the position of the line grooves (128), in which the protrusions (124) are accommodated, can be selected. The present invention aims to provide a strut bar for a vehicle, which is able to improve the structural stability of the vehicle.

    본 발명은 차량용 스트럿바에 관한 것으로, 내관(122)과 외관(126)의 이중관 구조를 이루는 바디(120)를 포함하되, 상기 내관(122) 외주면에는 길이방향을 따라 복수의 돌기(124)가 형성되는 한편 상기 내관(122) 내주면에는 상기 돌기(124)에 대응되는 라인홈(128)이 형성되어, 상기 돌기(124)가 상기 라인홈(128)에 수용되면서 상기 내관(122)이 상기 외관(126)에 끼워져 결합되어 비틀림 강성이 증가되고, 상기 라인홈(128)은 상기 돌기(124) 보다 적어도 2배의 개수로 형성되어 상기 내관(122)을 외관(126)에 끼우는 과정에서 상기 돌기(124)가 수용되는 라인홈(128)의 위치를 선택할 수 있게 되는 차량용 스트럿바에 관한 것이다.
