Abstract: The outer column has a press-fitted portion into which the inner column is press-fitted on the inner-diameter side, and an adjacent large diameter portion arranged in a location adjacent to the press-fitted portion in the axial direction and having an inner-diameter dimension larger than an inner-diameter dimension of the press-fitted portion. The inner-circumferential surface of the press-fitted portion and the outer-circumferential surface of the inner column come in contact with each other with an interference directly or via another member at only a plurality of contact locations separated in the circumferential direction. The column-side bracket is welded to an outer-circumferential surface of the adjacent large diameter portion with at least a part of the column-side bracket located on the outer-diameter side of the press-fitted portion.

Abstract: The front-side portion of an outer column includes a substantially cylindrical column main body portion having a pair of clamp portions and externally fitting with an inner column, and a reinforcing bridge portion that is integrally provided below the column main body portion. The front-side connecting portion of the reinforcing bridge portion includes a front-side inclined portion that inclines in a direction toward the front side going toward the upper side, and a rear-side connecting portion inclines in a direction toward the rear side going toward the upper side.

Abstract: The outer column 25 has a front-side small-diameter tubular portion 37 into which the inner column 24 is press fitted.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: Provided is a steering device in which a pair of tension springs is arranged on both outer sides in the width direction of a pair of support plate portions of a support bracket. The pair of tension springs applies a force directed diagonally upward toward the front to a base portion of an adjustment lever and a pressing plate arranged at both end portions of an adjustment rod, and elastically presses the front side surface of an engaging convex portion of a driven-side cam against a front side edge of a long hole in the up-down direction.

Abstract: Construction for reinforcing the strength of a pair of support plate sections is achieved. Upper end edges of the pair of support plate sections are fastened to a bottom surface of a bridge plate section of an installation plate section via lug sections for welding. A reinforcing member comprising a protrusion which is convex on the outside in the width direction and concave on the inside in the width direction is provided from the upper end section to the lower end section of the front-end section of each one of the pair of support plate sections.

Abstract: A steering device includes a steering column (4a), a support bracket (17a) attachable to a vehicle body to support the steering column, and a tightening mechanism (80). The steering column includes an outer column (11a) and an inner column (10a) partially enclosed by the outer column (11a). The tightening mechanism has a first state in which the steering column is tightened with the support bracket and a second state in which the tightening is released. The outer column includes a first surface (49a) and a second surface (49b) arranged spaced apart from each other in a first direction, which intersects an axial direction, and such that the first surface and the second surface is pressed by the support bracket in the first state, and includes a clamp part (38). The clamp part has a third surface (40) provided independently from the first surface and the second surface and such that the third surface is pressed by the support bracket in the first state.

Abstract: A steering column (4a) is configured such that a rear section of an inner column (10a) disposed on a front side of the steering column and a front section of an outer column (11a) disposed on a rear side of the steering column are displaceably set with respect to each other in an axial direction so that a total length of the steering column can be extended and contracted. A roller (70) is rotatably supported on a lower portion of a front end section of the outer column (11a) by a shoulder bolt (56) disposed in a width direction. An outer circumferential surface of the roller (70) is in contact with a lower surface of the inner column (10a).

Abstract: A pair of clamp parts (38 and 38) are provided on both sides of a front end portion of an outer column (11a) in a width direction and enclosed in three directions by slit portions. The clamp parts bend when an interval of inside surfaces of a pair of support plate units constituting an upper bracket is reduced so as to elastically sandwich an outer peripheral surface of an inner column (10a). First and second surfaces (49a and 49b) are provided on both sides of the outer column (11a) in the width direction and are spaced apart in a vertical direction such that each of the pair of clamp parts (38 and 38) is arranged therebetween, and such that torque acting on the outer column (11a) via the first and second surfaces is transmitted to inner surfaces of the support plate units.

Abstract: A tilt spring (72) is provided in a state being bridged between an upper bracket (17a) and an adjusting rod (24a). An upward biasing force is exerted on the adjusting rod (24a). A pair of rollers (63) are rotatably supported by the adjusting rod (24a). The force from the tilt spring (72) is transmitted to an outer column (11a) via the pair of rollers (63).
