According to the tie rod of the steering system for a vehicle according to the present invention, when the nut is rotated and rotated, the inner joint member and the outer joint member are rotated together at the same angle. The fastening operation of the ball joint and the outer ball joint can be easily performed.
The rotation interlocking means may be constituted by a groove formed on the outer circumferential surface of the inner ball joint by a predetermined length in the axial direction and a protruding portion protruding from the inner circumferential surface of the washer in the circumferential direction and engaged with the groove, The structure of the rotating interlocking means can be simplified and the relative rotation between the inner ball joint and the washer can be prevented during rotation of the nut, by constituting the engaging face formed by the engaging face and the flat face portion formed on a part of the inner peripheral face of the washer, Variation of the toein adjustment value can be prevented.
In addition, the washer is made of a ring-shaped elastic washer. By the elastic force in the axial direction of the washer in a state where the inner ball joint and the washer and the outer ball joint are in close contact with each other by tightening the nut, It is possible to effectively prevent the loosening of the nut by increasing the axial adhesion force between the parts.
