Construction of an outer column for a telescopic steering apparatus is achieved that maintains sufficient strength, and maintains smooth operation of the work of making it possible to adjust the forward-backward position of a steering wheel and maintaining the steering wheel at the adjusted position even when a steering-lock apparatus is assembled. An H-shaped slit 31 for expanding or contracting the inner diameter of a fitting-holding portion 30a of an outer column 10b comprises a main-slit section 39 and a pair of sub-slit sections 40a, 40b. Of the slit-end sections 41a, 41b, 42a, 42b of the sub-slit sections 40a, 40b, the rigidity in the direction of expansion or contraction of the width of the slit 31 in at least the portion where the closest-end section 41a that is located in a portion closest to a lock through hole 17b is formed is greater than the rigidity in the direction of expansion or contraction of the width of the slit 31 in the portions where the other slit-end sections 41b, 42a, 42b are formed. |
