The present invention relates to a motor power transmission shaft for adjusting an angle of a vehicle's steering column. The motor power transmission shaft for adjusting the angle of the vehicle's steering column according to the present invention is installed in a motor which performs a tilt function of the vehicle's steering column and transmits a power to the steering column through a flexible cable. The motor power transmission shaft is a rod-shaped structure having the outer circumferential surface of a cylindrical shape. A hollow unit is formed along a central axis, and the cross section of the hollow unit forms a rectangular structure. The motor power transmission shaft includes: an interference avoidance unit having the inner peripheral surface in a form of a circular cylinder having one end of the motor power transmission shaft larger than a maximum diameter of the flexible cable; and a noise suppression chamfer formed to be inclined toward the central axis of the hollow unit from the interference avoidance part. An object of the present invention is to reduce noise caused by friction with the flexible cable.

    본 발명에 따른 차량의 스티어링 컬럼 각도 조절용 모터 동력 전달 샤프트는, 차량의 스티어링 컬럼의 틸트 기능을 수행하는 모터 내에 설치되어 플렉시블 케이블을 통해 상기 스티어링 컬럼에 동력을 전달하는 모터 동력 전달 샤프트로서, 상기 모터 동력 전달 샤프트는, 외주면이 원통 형상인 로드 형태의 구조물이며, 중심축을 따라 중공부가 형성되며, 상기 중공부의 단면은 직사각형 구조를 형성하며, 상기 모터 동력 전달 샤프트의 일단부는 상기 플렉시블 케이블의 최대 직경 보다 큰 원형 실린더 형태의 내주면을 가지는 간섭 회피부; 및 상기 간섭 회피부로부터 상기 중공부의 중심축을 향해 경사지게 형성된 소음 억제 면취부를 포함한 것을 특징으로 한다.
