<p>PROBLEM TO BE SOLVED: To achieve a structure capable of stably holding an inner column 14c, on an inner diameter side of an outer column 13d.SOLUTION: An outer column 13d and a movable side bracket 22b are molded by integrally swelling by a hydroforming construction method or the like. Respective protrusion parts 23a and 23a for constituting a support part 26 of the outer column 13d and an outer peripheral surface of an inner column 14c are allowed to abut only in three places in a circumferential direction. Long holes 31 (31a) long in an axial direction are arranged in an intermediate part in a width direction of a bottom part 29 of the movable side bracket 22b. A pair of slits 33 and 33 are also formed in two positions for sandwiching the long holes in the circumferential direction.</p> |
