To provide an intermediate shaft for steering devices which suppresses whirling caused by bending of the intermediate shaft even when external force has been received, while restricting an increase in costs, and which can suppress generation of vibration and abnormal sound, and to provide a steering device.SOLUTION: An intermediate shaft for steering devices includes: a female shaft 10 which has a first female spline part 17 on an inner peripheral surface of one section in a shaft direction, and a second female spline part 19 on an inner peripheral surface of the other section in the shaft direction, and whose both ends are open; and a first male shaft 30 having a first male spline part 31 on an outer peripheral surface; and a second male shaft 40 having a second male spline part 41 on the outer peripheral surface. The first male spline part 31 of the first male shaft 30 is spline-engaged with the first female spline part 17 of the female shaft 10, whereas the second male spline part 41 of the second male shaft 40 is spline-engaged in a press-fitted manner with the second female spline part 19 of the female shaft 10. A sliding load of the first male shaft 30 on the female shaft 10 is smaller than a sliding load of the second male shaft 40 on the female shaft 10.SELECTED DRAWING: Figure 2

    【課題】コストの増大を抑えつつ、外力を受けた場合でも中間軸の曲がりによる振れ廻りが抑えられ、振動や異音の発生を抑制できるステアリング装置用中間軸、及びステアリング装置を提供する。【解決手段】軸方向一方部の内周面に第1雌スプライン部17を有し、軸方向他方部の内周面に第2雌スプライン部19を有する両端が開口した雌軸10と、外周面に第1雄スプライン部31を有する第1雄軸30と、外周面に第2雄スプライン部41を有する第2雄軸40と、を備え、雌軸10の第1雌スプライン部17に第1雄軸30の第1雄スプライン部31がスプライン係合し、雌軸10の第2雌スプライン部19に第2雄軸40の第2雄スプライン部41が圧入状態でスプライン係合し、雌軸10に対する第1雄軸30の摺動荷重は、雌軸10に対する第2雄軸40の摺動荷重より小さい。【選択図】図2
