摘要： 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.

摘要： Construction is achieved that makes it possible to easily determine whether or not a combination of a drive-side cam and driven-side cam is suitable. Driven-side concave grooves 47 that are depressed inward in the radial direction and extend along the axial direction are formed in the outer-circumferential surface of the driven-side cam 30a at two locations on opposite sides in the radial direction. First drive-side concave grooves 45 that are depressed inward in the radial direction and extend along the axial direction are formed in portions of the outer-circumferential surface of the drive-side cam 29a such that the phase thereof in the circumferential direction in the locked state coincides with that of the driven-side concave grooves 47, and second drive-side concave grooves 46 that are depressed inward in the radial direction and extend along the axial direction are formed in portions of the outer-circumferential surface of the drive-side cam 29a such that the phase thereof in the circumferential direction in the unlocked state coincides with that of the driven-side concave grooves 47.

摘要： Construction of an outer column for a telescopic steering apparatus is achieved in which sufficient strength is maintained even when a steering lock apparatus is assembled, and smooth operation is maintained when making it possible to adjust the forward/backward position of a steering wheel, and when maintaining the adjusted position. Of the end sections 58a, 58b, 59a, 59b of the sub slit sections 52a, 52b of an H-shaped slit 19a for expanding or contracting the inner diameter of a fitting support portion 31a of an outer column 11b, the rigidity of the nearest end section 58a portion that exists in the location closest to a lock through hole 37a and of the furthest end section 59a portion that exists in a location diagonally from the nearest end section 58a, is greater than the rigidity of the end section 58b, 59b portions in the remaining two locations. Moreover, convex sections 61a, 61b are provided at two location in the up/down direction on the outside surfaces of each of a pair of held plate sections 20a, 20b.
