PROBLEM TO BE SOLVED: To effectively prevent the thrust-up of a steering wheel by allowing the backward movement of a steering mechanism caused by primary collision in a wider range by a limited-length intermediate shaft in front-side collision of a vehicle. SOLUTION: The intermediate shaft 5 connecting a column shaft to the steering mechanism has a first cylindrical shaft 51 and a second shaft 52 internally fitted and connected thereto via a connection pin 55 driven in the radial direction. In one of two pin holes 53, 53 formed passing through the peripheral wall of the first shaft 51 in radial opposition to each other where the connection pin 55 is driven, a narrower oblong hole 56 is continuously provided toward the end of the first shaft 51, and in the other, a narrower oblong hole 57 is continuously provided toward the base end of the first shaft 51. When force is applied to the intermediate shaft 5 in a direction of its shaft length, the connection pin 55 is tilted with the oblong holes 56, 57 as guides to cause the first shaft 51 and the second shaft 52 to be bent.
