To provide an intermediate shaft enabling smooth telescopic operation to be performed and keeps water from entering from an outer space into an internal space of a female shaft.SOLUTION: An intermediate shaft 6 includes: a female shaft 10; a male shaft 11; and a seal ring 12 blocking an end part opening on an axial rear side of a clearance present between an inner peripheral surface of a cylinder part 13 of the female shaft 10 and an outer peripheral surface of the male shaft 11. The male shaft 11 has an axial hole 26 and a lateral hole 27. The axial hole 26 extends in an axial direction at a radial center part of the male shaft 11 and is open only in an end surface on the axial front side out of the end surfaces on opposite axial sides of the male shaft 11. The lateral hole 27 has an outer opening part that is always open in a portion positioned on the axial rear side relative to a seal ring 12 during use, and an inner opening part that is open in an inner peripheral surface of the axial hole 26, on a peripheral surface of the male shaft 11.SELECTED DRAWING: Figure 1

    【課題】円滑な伸縮動作を行わせることができ、かつ、雌軸の内部空間に外部空間から水が入り込みにくい中間シャフトを提供する。【解決手段】中間シャフト6は、雌軸10と、雄軸11と、雌軸10の筒部13の内周面と雄軸11の外周面との間に存在する隙間の軸方向後側の端部開口を塞ぐシールリング12とを備える。雄軸11は、軸方向孔26および横孔27を有する。軸方向孔26は、雄軸11の径方向中心部において軸方向に伸長し、かつ、雄軸11の軸方向両側の端面のうち、軸方向前側の端面にのみ開口している。横孔27は、雄軸11の外周面のうち、使用時において常にシールリング12よりも軸方向後側に位置する部分に開口する外側開口部と、軸方向孔26の内周面に開口する内側開口部とを有する。【選択図】図1
