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 approximately 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.
