Abstract:
A steering shaft, comprising:an outer shaft having axially extending inner splines formed around an inner surface thereof, the inner splines including teeth;an axially directed inner shaft includinga splined portion having axially extending outer splines formed around an outer surface thereof, anda shaft portion including a retaining portion having axially extending grooves formed around an outer surface of the shaft portion;a sliding coupling section formed by a coupling portion of the outer shaft and a coupling portion of the inner shaft so as to allow the outer shaft and the inner shaft to be telescopically slidable in the axial direction relative to each other by means of the inner and outer splines; anda sliding resin member filling a space formed in the sliding coupling section between an opening portion of the outer shaft and the retaining portion of the inner shaft, the sliding resin member respectively including inner and outer peripheries sized and arranged to engage and interlock with the grooves of the inner shaft and the teeth of the inner splines of the outer shaft, to thereby prevent rotational displacement in a circumferential direction between the inner and outer shafts.
