  • Patent number: 11511788
    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.

  • Patent number: 10093340
    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.

  • Patent number: 10065671
    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).

  • Patent number: 10059363
    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.
