Abstract
A steering column device includes a male screw shaft member supported by an outer column and a female screw member provided in a link member. The female screw member and the male screw shaft member are moved relative to each other by rotation of the male screw shaft member, causing the link member to swing relative to the outer column. The female screw member includes a main body section supported by the link member, a fragile section provided on one side of the main body section, and a screw engaging section provided on the opposite side of the fragile section from the main body section. In a state where an adjust nut is screwed to the screw engaging section, a distal end portion of the adjust nut comes into contact with the main body section and extends the fragile section in the axial direction of the male screw shaft member.
