Title:
STEERING COLUMN AND STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/085243
Kind Code:
A1
Abstract:
A structure is realized in which the sliding resistance in the axial direction between an inner column and an outer column can easily be contained within an appropriate range. The present invention comprises: the inner column 24; the outer column 25; and a column side bracket 26 fixed by welding to the outer circumferential surface of the outer column 25. The outer column 25 has a front-side small-diameter cylindrical part 37 that is a press-fitted part into which the inner column 24 is press-fitted on the inner-diameter side. The inner circumferential surface of the front-side small-diameter cylindrical part 37 and the outer circumferential surface of the inner column 24 contact in a state having a fastening margin, directly, or via another member, in only a plurality of contact locations separated in the circumferential direction. In the column side bracket 26, at least one location in the axial direction is welded to the outer circumferential surface of the front-side small-diameter cylindrical part 37 in only two weld locations that are close in the circumferential direction.
