To provide a steering shaft configured so that slide resistance between a tooth part of an inner shaft and a tooth part of an outer shaft can be reduced further.SOLUTION: A steering shaft comprises: an inner shaft that has a first tooth on an outer peripheral surface and extends in an axial direction along a central shaft; an outer shaft that has a second tooth part on an inner peripheral surface and is arranged at an outer periphery side of the first tooth part; a resin layer arranged between the first tooth part and the second tooth part; and an annular hole cover provided at an outer periphery side of the outer shaft. The hole cover comprises a plurality of bellows arranged across a hollow part and is arranged to overlap with the resin layer when viewed from a radial direction.SELECTED DRAWING: Figure 5

    【課題】インナーシャフトの歯部とアウターシャフトの歯部との間の摺動抵抗をより低減することが可能なステアリングシャフトを提供すること。【解決手段】ステアリングシャフトは、外周面に第1歯部を有し且つ中心軸に沿った軸方向に延びるインナーシャフトと、内周面に第2歯部を有し且つ第1歯部の外周側に配置されるアウターシャフトと、第1歯部と第2歯部との間に配置される樹脂層と、アウターシャフトの外周側に設けられる環状のホールカバーと、を備え、ホールカバーは、中空部を挟んで配置される複数のベローズを備え、且つ径方向から見た場合に樹脂層と重なるように配置される。【選択図】図5
