Abstract: Construction is achieved that, when performing operation in order to maintain the position of a steering wheel after adjustment, is capable of reducing the operation torque that is applied to an adjustment lever 14 during the first half of the operation, and is capable of improving operability. Portions (virtual sliding-contact section lines M) of the drive-side cam surfaces 20a that can come in sliding contact with the driven-side continuous surfaces 24a when moving from a state in which the position of the steering wheel can be adjusted to a state in which the adjusted position can be maintained, are inclined toward one side in the circumferential direction at the time when the virtual sliding-contact section lines M overlap one end N1 in the circumferential direction of the driven-side continuous surfaces 24a. As a result, during operation, the areas of sliding contact between the drive-side cam surface 20a and the driven-side continuous surfaces 24a gradually increase from the inside end in the radial direction to the outside in the radial direction.

Abstract: A steering apparatus includes a steering shaft, a column rotatably supporting the steering shaft, a bracket attached to the column, a capsule configured to be fixed to a vehicle body and having upper and lower holding plates sandwiching the flange portion, a coupling part coupling the flange portion and the capsule such that the flange portion is detachable from the capsule by an impact force toward the front of the vehicle body, a rounded portion formed at a front end portion of the flange portion with a curvature radius varying along a vehicle-width direction, and an energy-absorbing member. The energy-absorbing member includes a rear portion engaged with the capsule, a front extension portion extending forward from the rear portion, a bent portion bent in front of the rounded portion, and a rear extension portion extending rearward and inclined in the vehicle-width direction with respect to the column center axis.

Abstract: Construction of a steering-column apparatus is achieved that is capable of keeping the force required for expanding or contracting the portion 33 where an inner column 10a fits and is supported small, and improves the ease of operation for adjusting the position of a steering wheel 4. A split 19a that is provided in the bottom surface of the front section of an outer column 11a comprises: a main slit section 36 that extends in the axial direction; and a sub slit section 37 that is formed in the circumferential direction of the front-end section of the main slit section 36, with the front-end section of the main slit section 37 being open on the edge on the rear side thereof. The length in the circumferential direction from the main slit section 36 to one end section in the circumferential direction of both end sections in the circumferential direction of the sub slit section 37, is longer than the length in the circumferential direction from the main slit section 36 to the other end section in the circumferential direction, so the rigidity in the width direction of one half section in width direction of the outer column 11a where one supported section 20a is located, is less than the rigidity in the width direction of the other half section in the width direction where another supported section 20b is located.
