摘要： In a method of manufacturing a shock absorbing type steering shaft, the fore end portion of a tubular outer shaft having a female serration formed on the inner peripheral surface thereof and the fore end portion of an inner shaft having a male serration formed on the outer peripheral surface thereof are brought into engagement with each other, and then the fore end portions of the two shafts are plastically deformed in the diametral direction thereof. Thereafter, the outer shaft and the inner shaft are displaced relative to each other toward each other in the axial direction thereof. The fore end portion of the small-diametered portion of the outer shaft is then pressure-fitted into the base end portion of the large-diametered portion of the inner shaft. At the same time, the fore end portion of the large-diametered portion is pressure-fitted into the base end portion of the small-diametered portion. Also, the intermediate portion of the small-diametered portion and the intermediate portion of the large-diametered portion are brought into loose engagement with each other.
