PROBLEM TO BE SOLVED: To provide a steering shaft that is able to reduce a manufacturing cost through a reduction in the number of components and that is also able to make steering operability satisfactory.SOLUTION: An upper shaft 1 for a steering shaft S is provided with: a first engagement part 11 in which the final end of this upper shaft 1 has a non-circular, cylindrical form; and a second engagement part 12 located further on the leading-end side from the first engagement part 11, and into which one end of a torsion bar 3 is fitted so as to be relatively unrotatable. A lower shaft 2 is provided with an irregular part 20, the contour of the outer periphery of which is non-circular in a cross-section. A rotation restricting part R for restricting relative rotation of the upper and lower shafts 1, 2 beyond a predetermined angle is configured such that the irregular part 20 is fitted in the first engagement part 11 with a play.SELECTED DRAWING: Figure 1

    【課題】部品点数の削減による製造コストの低減を図ることができ、かつステアリング操作性も良好なものとすることが可能なステアリングシャフトを提供する。【解決手段】ステアリングシャフトSのアッパシャフト1には、このアッパシャフト1の終端部が非円筒形の筒状の形態とされた第1の嵌合部11、およびこの第1の嵌合部11よりも先端部寄りに位置し、かつトーションバー3の一端部が相対回転不能に嵌入される第2の嵌合部12が設けられており、ロアシャフト2には、外周の輪郭が断面視非円形状の異形部20が設けられ、アッパおよびロアシャフト1,2が所定角度を超えて相対回転することを規制するための回転規制部Rは、異形部20が第1の嵌合部11に遊びをもって嵌入した構成とされている。【選択図】 図1
