According to the present invention, a steering column shaft comprises: a first shaft member made of aluminum; and a second shaft member including a locking sleeve having a locking tooth for an anti-theft function and made of an iron material. The first shaft member and the second shaft member are manufactured separately and then fixed to each other. Since the second shaft member including the locking tooth for an anti-theft function requiring strength is formed by forging with an iron material and the first shaft member is made of a lightweight aluminum material, and the two members are then combined, weight reduction can be achieved while ensuring the strength of the locking teeth for the anti-theft function.

    스티어링 칼럼 샤프트는 알루미늄 재질의 제1 샤프트 부재, 그리고 도난 방지 기능을 위한 잠금 치를 구비하는 잠금 슬리브를 구비하며 철 재질로 형성되는 제2 샤프트 부재를 포함한다. 상기 제1 샤프트 부재와 상기 제2 샤프트 부재는 별도로 제조된 후 서로 고정된다. 강도가 요구되는 도난 방지 기능을 위한 잠금 치를 포함하는 제2 샤프트 부재가 철 재질로 단조에 의해 형성되고 제1 부재는 경량의 알루미늄 재질로 형성한 후 양자를 결합함으로써, 도난 방지 기능을 위한 잠금 치의 강도를 확보하면서도 무게 감소를 달성할 수 있다.
