The present invention realizes a steering shaft having a structure capable of suppressing a change in sliding resistance even when the entire length is changed. Any one of the inner diameter side clamping part (19) and the outer diameter side clamping part (31) is provided with at least one non-clamping part (23) which is not clamped with the other clamping part at the middle part in the axial direction, and clamping parts which respectively have an effective length X are arranged on the two sides of the non-clamping part (23) of the one clamping part in the axial direction. The non-engagement section (23) has an axial dimension that is the same length as the effective length X, and the other engagement section has an effective length Y that is a length 2X that is twice the effective length X.

    本发明实现在使全长变化时也能够抑制滑动阻力的变化的构造的转向轴。内径侧卡合部(19)和外径侧卡合部(31)的任一方的卡合部在轴向的中间部具备不与另一方的卡合部卡合的至少一个非卡合部(23),在上述一方的卡合部的非卡合部(23)的轴向两侧配置可卡合部,该可卡合部分别具有有效长度X,非卡合部(23)具有长度与有效长度X相同的轴向尺寸,并且上述另一方的卡合部具有有效长度X的2倍的长度2X的有效长度Y。
