To provide a telescopic shaft improved in reliability.SOLUTION: A telescopic shaft 10 is equipped with an inner shaft 30, an outer shaft 20, and a sliding member 50. The inner shaft 30 has an outer tooth portion 31 formed on an outer peripheral surface 30a, and the outer tooth portion 31 includes a plurality of teeth 32 aligned in a circumferential direction. The outer shaft 20 has an inner tooth portion 21 formed on an inner peripheral surface 20a, and the inner tooth portion 21 includes a plurality of teeth 22 disposed at a position where it is engaged with the outer tooth portion 31. The sliding member 50 is disposed between the outer tooth portion 31 and the inner tooth portion 21, is fixed to the outer tooth portion 31, and is disposed so as to axially slide with respect to the inner tooth portion 21. The sliding member 50 has a wall portion 55 projecting toward the inner tooth portion 21 at an axial end portion in an axially extending gap 59 between the sliding member 50 and the inner tooth portion 21.SELECTED DRAWING: Figure 7

    【課題】信頼性が向上された伸縮軸を提供すること。【解決手段】伸縮軸10は、内軸30と、外軸20と、摺動部材50とを備える。内軸30は、外周面30aに形成された外歯部31を有し、外歯部31は、周方向に並べられた複数の歯32を含む。外軸20は、内周面20aに形成された内歯部21を有し、内歯部21は、外歯部31に噛み合う位置に配置された複数の歯22を含む。摺動部材50は、外歯部31及び内歯部21の間に配置され、かつ、外歯部31に対して固定されており、内歯部21に対して軸方向に摺動可能に配置されている。摺動部材50は、摺動部材50と、内歯部21との間の、軸方向に延在する隙間59における軸方向の端部に、内歯部21に向けて突出する壁部55を有する。【選択図】図7
