A reducer of a vehicle steering column according to the present embodiments includes: a housing that is coupled to the steering column and is provided with a motor shaft rotated by a motor and an output shaft rotated in association with the motor shaft; a ball stud coupled to at least one of the motor shaft or the output shaft; a ball seat in which the ball stud is inserted and one side is supported on the housing; and a housing cover supported on the other side of the ball seat and coupled to the housing. Accordingly, a ball joint structure is applied to the reducer that performs a tilt or telescope function of the steering column, so that axial and radial movement is suppressed and friction is minimized to reduce noise and improve durability when the motor shaft and the output shaft rotate, and the number of parts is reduced and assembly is facilitated, so that productivity can be improved and costs can be reduced.

    본 실시예들에 의한 자동차 조향컬럼의 감속기는, 조향컬럼에 결합되고, 모터에 의해 회전되는 모터축 및 모터축과 연동되어 회전되는 출력축이 구비되는 하우징, 모터축 또는 출력축 중 적어도 어느 하나에 결합되는 볼스터드, 볼스터드가 삽입되고 일측이 하우징에 지지되는 볼시트, 볼시트의 타측에 지지되며 하우징에 결합되는 하우징커버를 포함하여, 조향컬럼의 틸트 또는 텔레스코프 기능을 수행하는 감속기에 볼조인트 구조를 적용함으로써 모터축, 출력축 등이 회전할 때 축방향 및 경방향 유동을 억제하고 마찰을 최소화하여 노이즈가 저감되고 내구성이 향상되며, 부품 수를 감소시키고 조립을 용이하게 하여 생산성이 향상되고 원가가 절감될 수 있다.
