To provide an intermediate shaft for a steering device which can prevent removal of a yoke of a universal joint and a shaft while reducing manufacturing costs.SOLUTION: An intermediate shaft for a steering device includes: a yoke 31 of a universal joint 30 formed with a coupling hole 33 having a hole side serration 34 on an inner peripheral surface; and a shaft 11 in which a shaft side serration 14 to be fitted with the hole side serration 34 is formed on an outer peripheral surface and which is fitted in the coupling hole 33. The yoke 31 has: a base 32 in which the coupling hole 33 is formed; and a yoke arm 37 extending from the base 32. The shaft 11 which is fitted in the coupling hole 33 has a first swage part 21 and a second swage part 22 protruding to the radial outer side of the shaft 11 in a portion at the side where the yoke arm 37 is located. The second swage part 22 is disposed having a straight part 16 at the shaft side serration 14 between itself and the base 32. The first swage part 21 is disposed without having the straight part 16 of the shaft side serration 14 between itself and the base 32.SELECTED DRAWING: Figure 4

    【課題】製造コストを抑えつつ、自在継手のヨークとシャフトとの抜け止めを行うことのできるステアリング装置用中間シャフトを提供すること。【解決手段】内周面に孔側セレーション34を有する結合孔33が形成される自在継手30のヨーク31と、孔側セレーション34に圧入される軸側セレーション14が外周面に形成され、結合孔33に嵌合するシャフト11と、を備え、ヨーク31は、結合孔33が形成される基部32と、基部32から延びるヨークアーム37とを有し、結合孔33に嵌合するシャフト11は、ヨークアーム37が位置する側の部分にシャフト11の径方向外側に突出する第1カシメ部21と第2カシメ部22とを有し、第2カシメ部22は、基部32との間に軸側セレーション14における直線部16を有して配置され、第1カシメ部21は、基部32との間に軸側セレーション14の直線部16を有さずに配置される。【選択図】図4
