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: 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.

Abstract: A steering device including a steering column supporting a steering shaft to be coupled to a steering wheel. The steering column is sandwiched between a bracket including a first support plate and a second support plate with a tightening shaft penetrating the first support plate and the second support plate and including a male thread at an end of the tightening shaft on a side close to the second support plate having a nut attached thereon. An operation lever is disposed between the nut and the second support plate and penetrated by the tightening shaft. A case including a bottom surface facing an end surface of the tightening shaft is attached to the operation lever, and a coil spring coming into contact with the bottom surface and the tightening shaft.

Abstract: An upper surface of a front portion of an outer column is provided with a slit having a substantial T shape as seen from a radial direction and a pair of sandwiched portions. In a rear end side portion of an outer surface of the sandwiched portion, a dented portion is formed to be dented inward in a width direction at a lower half portion thereof. Accordingly, a distance from the position of a force which acts on the sandwiched portions according to an operation on an adjustment lever to a position of a main outer column body which is a fulcrum of elastic deformation becomes longer. Therefore, a structure capable of reducing change of a force necessary for operating the adjustment lever and stably fitting and holding an inner column regardless of the position of a steering wheel in a front-rear direction is implemented.
