Abstract: A steering apparatus includes a key lock collar (5) fitted on a steering shaft (2) and restricted from rotating by a steering lock mechanism when performing a steering lock, and a cylindrical slip ring (7) interposed between the steering shaft (2) and the key lock collar (5) in radial directions. The slip ring (7) includes a plurality of protruded portions (8) protruding outwardly or inwardly in the radial directions and being provided in a circumferential direction, and an axis-directional portion of the steering shaft (2) covered by the slip ring (7) is formed with a large-diameter portion (10a) and a small-diameter portion (10b), thereby further stabilizing slip torque of the key lock collar (5) and enlarging a range of a dimensional allowance.

Abstract: A steering device contains a rolling bearing that axially supports a steering shaft to allow rotation, and whose upper column and lower column engage along the axis in a sliding motion in order to provide improved steering wheel operating stability during high-speed driving. The elastic force of an O-ring tightens the outer circumferential surface of a female steering shaft against the cylindrical surface of a bushing. A specific frictional force therefore occurs between the cylindrical surface of the bushing and the outer circumferential surface of the female steering shaft so that handling stability of the steering wheel during high-speed driving is improved. Moreover, vehicle vibrations are prevented from being conveyed to the steering wheel by the O-ring crushed due to the pressing force of the inner circumferential surface of the first lower column and that absorbs the vibration of the female steering shaft.

Abstract: End portions of lower-side telescopic friction plates 61, 61 which lie to face a front side of a vehicle body are connected integrally by a connecting portion 612, and a lower end 617 of the connecting portion 612 is fixed to an outer circumference of an upper-side lower column 10A by means of welding. When an upper column 11 is fastened on to a vehicle body mounting bracket 3 for tilt and telescopic positioning of the upper column 11, the lower-side telescopic friction plates 61 and upper-side telescopic friction plates 62 are fastened together. The upper column 11 and the lower column 10 are connected together via the lower-side telescopic friction plates 6 and the upper-side telescopic friction plates 62, whereby the rigidity and vibration properties of a steering apparatus as a whole are enhanced.

Abstract: A steering device which, having a movable wedge smoothly movable to clamp a column, is capable of a secure clamping operation is provided. A center axis of a column clamp shaft is disposed to pass through a middle position of a length of contact between a slope of a first wedge and a slope of a third wedge and a middle position of a length of contact between a slope of a second wedge and another slope of the third wedge. Pressing forces to which the first and second wedges are subjected when a column is clamped act on the middle positions of the lengths of contact, so that no rotational moment is applied to the first and second wedges. The first and second wedges can therefore move smoothly over the slopes of the third wedge, respectively.
