The invention discloses a steering shaft and an automotive steering mechanism. The steering shaft comprises a sleeve and an inner shaft, wherein one end of the sleeve sleeves one end of the inner shaft; at least three axial grooves are distributed in the inner shaft in the peripheral direction; clamping grooves corresponding to the axial grooves are formed in the sleeve; elastic transmission assemblies are respectively distributed in the axial grooves; each elastic transmission assembly comprises a rigid assembly, a transmission block and an elastic assembly; one end of each rigid component is clamped in the corresponding clamping groove; one end of each transmission block is propped against the groove wall of the corresponding axial groove, and the other end of the transmission block is propped against the corresponding rigid assembly in the peripheral direction of the inner shaft; one end of each elastic assembly is propped against the groove wall of the corresponding axial groove, and the other end of the elastic assembly provides propping force for the corresponding rigid component in the radial direction of the inner shaft. According to the steering shaft provided by the invention, the elastic transmission assemblies are arranged between the sleeve and the inner shaft, and the dimension added by the restoration of the elastic assemblies makes up for the wear dimension of the rigid assemblies, so that the problem that a gap between the sleeve and the inner shaft is enlarged when the sleeve and the inner shaft are used for a long term is solved.
