Claims

[Scope of utility model registration request]

A bendable and deformable steering shaft made by dividing any of the shafts constituting the steering shaft, such as a main shaft or an intermediate shaft, into two and connecting these two divided shafts at their opposing ends via a coupling mechanism. wherein the coupling mechanism is bent from mutually axially symmetrical positions at the base portion fixed to the opposing ends of one of the split shafts and extending radially outward, and the outer end of the base plate portion. at least one pair of arms extending toward the other split shaft; and a base plate fixed to the opposite end of the other split shaft and extending radially outward and fixed to both arms, or the base plate and its outer end; and at least a pair of arms bent from mutually axially symmetrical positions and extending toward one of the split shafts and fixed to both arms, and the base plate or the arms are aligned with the axis of the split shaft. A steering shaft capable of bending and deforming, characterized in that it is provided at an angle.
