An intermediate shaft for a vehicle steering device, according to the present invention, comprises: a yoke tube; and a yoke shaft of which one end is inserted into one end of the yoke tube and which is movable in the axial direction with respect to the yoke tube, wherein the yoke shaft has formed in the other end thereof a plurality of corrugated portions absorbing the impact, and the plurality of corrugated portions are recessed inward with respect to the outer circumference of the other end of the yoke shaft. Thus, there is an advantage of improved impact absorption in the case of vehicle collision.
La présente invention concerne un arbre intermédiaire pour un dispositif de direction de véhicule qui comprend : un tube d'étrier ; et un arbre d'étrier dont une extrémité est insérée dans une extrémité du tube d'étrier et qui est mobile dans la direction axiale par rapport au tube d'étrier, l'arbre d'étrier ayant formé dans son autre extrémité une pluralité de parties ondulées absorbant l'impact, et la pluralité de parties ondulées étant en retrait vers l'intérieur par rapport à la circonférence externe de l'autre extrémité de l'arbre d'étrier. Ainsi, il existe un avantage d'une absorption d'impact améliorée dans le cas d'une collision de véhicule.
본 발명에 따른 차량 조향장치용 인텀 샤프트는, 요크 튜브와, 상기 요크 튜브의 일단부로 일단부가 삽입되어 상기 요크 튜브에 대해 축방향으로 이동 가능한 요크 샤프트를 포함하고, 상기 요크 샤프트의 타단부에는 충격을 흡수하는 복수개의 주름부가 축방향을 따라 형성되고, 상기 복수개의 주름부는 상기 요크 샤프트의 타단부의 외주면에 대해 내측으로 함입 형성되어, 차량 충돌 시 충격흡수 성능이 향상되는 이점이 있다.
