portions is made to be an input shaft 23, a connecting
cylinder 19 to which the input shaft is serration-fitted
is integrally provided at a lower portion of the steering
shaft, a side wall of the connecting cylinder is provided
with a groove 19b in the axial direction, fastening means
(20, 21, 22) are provided for reducing the diameter of
