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: 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: A steering device includes a pressing plate provided in a section of the adjustment rod protruding from the outside surface of one support plate section as a locked member. The pressing plate has a circular plate body externally fitted onto the adjustment rod and a locking plate section as an extended arm section. A tension spring is bridged between a section shifted in the width direction from the plate body of the locking plate section and the support bracket.

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).

Abstract: In an upper end portion of a front end portion of an outer column, a cutout which is opened to a front end edge of the outer column is provided in a state of being overlapped on a front end portion of an outer shaft in a radial direction. Accordingly, during insertion work, a state of core dislocation can be visually confirmed through the cutout.

Abstract: A steering device includes a fixed bracket, a movable bracket, a friction plate, a first friction washer, a pressing plate, engagement units, a second friction washer, and a fastening tool. The friction plate is attached to face, with an appropriate gap, at least one of both fixed side portions of the fixed bracket. The first washer is inserted between the fixed side portion and the friction plate. The pressing plate is attached to an outer surface of the friction plate. The engagement unit causes the pressing plate to be detachably attached and be immovable at least in a vertical direction. The second friction washer is clamped between the pressing plate and the friction plate. The fixed bracket, the friction plate, the first friction washer, the second friction washer, and the pressing plate are connected by penetrating therethrough a lock bolt of the fastening tool.

Abstract: A steering apparatus includes a fixed bracket, a fastener, a primary cam that rotates with a rotation operation of the fastener, and a secondary cam that is non-rotatably attached to a fixed side portion and is in contact with the primary cam. Cam operating portions each including an inclined surface portion, a high level surface, and a contact protrusion are formed at regular intervals along a circumferential direction on a base flat surface of each of the primary cam and the secondary cam, and the inclined surface portion is constituted by a low gradually inclined surface, a middle sharply inclined surface, and a high gradually inclined surface arranged in this order from the base flat surface toward the high level surface.
