Claims (1)

[Scope of utility model registration request] A slit is provided in a steering shaft consisting of either a steering main shaft or an intermediate shaft, and a bending deformation portion extending in the shaft axis direction bends and deforms when torsion is applied to the shaft; A torsion spring type steering shaft is characterized in that a stopper part is formed in which the slit disappears when the slit disappears and both edges of the slit come into contact to suppress further torsional deformation of the shaft.
