The present invention provides a tilt fixing device for a vehicular steering column configured such that, during a tilt locking operation by the driver, the steering column can be stably locked without causing the tooth-on-tooth phenomenon between the stationary gear and the movable gear. The tilt fixing device for a vehicular steering column according to one embodiment of the present invention includes: a tilt bracket coupled to an outer side of a steering column and provided at both sides thereof with tilt guides coupled to an outer side of a distance bracket, in which a tilt hole is formed in each tilt guide, and a fixed gear in the form of a first thread is formed on a side of one tilt hole; a movable gear installed outside the tilt guide, meshed with the fixed gear and moving along the fixed gear; a load transmission unit for preventing the movable gear from disengaging from the fixed gear and transmitting a load in an axial direction during a tilting operation of the steering column; a wave washer-shaped elastic member which is positioned between the movable gear and the load transmission unit, generates an elastic force when the movable gear and the load transmission unit are engaged with each other and supports the frictional force; a lever bolt extending through the tilt bracket, the movable gear, the wave washer-shaped elastic member, and the load transmission unit and moving along the first tilt hole; and a locking unit coupled to an end of the lever bolt and configured to limit the movement of the lever bolt by fixing the movable gear having the lever bolt inserted therein such that the movable gear is meshed with the fixed gear.

    본 발명의 일 실시예는, 조향컬럼의 외측에 결합되고, 양측에 틸트 가이드부가 구비되며, 상기 틸트 가이드부에 각각 제1 틸트홀이 형성되며, 하나의 제1 틸트홀 일측에 제1 나사산 형태의 고정기어가 형성된 틸트 브래킷; 상기 틸트 가이드부의 외측에 설치되고, 상기 고정기어에 치합되며, 상기 고정기어를 따라 이동하는 가동기어; 상기 고정기어로부터 상기 가동기어가 이탈하는 것을 방지하고, 상기 조향컬럼의 틸팅 동작 시에 축방향으로 하중을 전달하는 하중 전달부; 상기 가동기어와 상기 하중 전달부 사이에 위치하여, 상기 가동기어와 상기 하중 전달부 간의 결합 시에 탄성력을 발생시키고 마찰력을 지지하는 웨이브와셔형 탄성부재; 상기 틸트 브래킷과 상기 가동기어, 상기 웨이브와셔형 탄성부재 및 상기 하중 전달부를 관통하여 설치되며, 상기 제1 틸트홀을 따라 이동하는 레버볼트; 및 상기 레버볼트의 단부에 결합되며, 상기 레버볼트가 삽입된 상기 가동기어가 상기 고정기어에 치합되도록 고정하여 상기 레버볼트의 이동을 제한하는 잠금유닛을 포함하는 차량의 조향컬럼용 틸트 고정 장치를 제공한다.
