Abstract: To provide a steering wheel position adjustment device in a steering device comprising a tilt telescopic adjustment mechanism, in which there is almost no change in operation feeling, particularly prior or posterior to telescopic adjustments, and that can maintain good operation feeling. A column housing, through which a column pipe passes and is fixed thereto, is fitted to a fixed bracket so that the column housing can either freely move or be fixed in the axial direction. The column pipe is inserted slidably in an insertion hole of a pivot housing that is fitted to be able to swing freely and be fixed freely to the front of the column housing in the axial direction. An upper shaft is provided, within the column pipe, that moves together with the column pipe in the axial direction. A lower shaft is provided in the pivot housing. The upper shaft transmits rotation to the lower shaft, and the upper shaft and the lower shaft are connected to be able to slide freely relative to each other.

Abstract: A shock absorbing apparatus for a steering column includes: a sliding capsule having a collar portion fixed immovably to a vehicle body; and a column bracket having a shock absorbing hole which is elongated in a longitudinal direction of a steering column and in which a fixing through-hole portion on one end side of the elongated hole, a first shock absorbing portion having a shaft-like member in a vicinity of the fixing through-hole portion, and a second shock absorbing portion having a crushable inner peripheral edge at a side edge of the elongated hole are substantially continuously formed in the longitudinal direction. During a collision, the collar portion bends the shaft-like member and crushes the second shock absorbing portion to thereby absorb colliding energy.

Abstract: The present invention relates to a steering device of the type which carries out tilt/telescopic adjustments using front-back dual-location clamping/fastening bolts disposed at front and back, two locations, and has objects to stabilize and improve operation at the time of a tilt/telescopic adjustment thereof, and to provide better lever operation feeling.

Abstract: An intermediate shaft apparatus of a steering shaft assembly includes: an input shaft; a coupling shaft fixed to the input shaft in a circumferential direction and arranged to be slidable relative to the input shaft in an axial direction only during application of an impact thereto; an output shaft fixed to the coupling shaft in the circumferential direction and arranged to be slidable in the axial direction; and a buffer joint fitted at an axial end portion of the output shaft and formed by coupling an output-side yoke member and a cup member via an elastic member, wherein the output shaft and the cup member are provided with a penetrating portion through which the coupling shaft is capable of penetrating in the axial direction.

Abstract: An elastic coupling for a steering apparatus includes: a thin-walled tubular member; a joint arm which is joined and fixed to the tubular member; an engaging through hole portion formed in a joining portion for joining the tubular member and the joint arm; an elastic bearing member fitted to an inner periphery of the tubular member; and a shaft fitted in the tubular member via the elastic bearing member and adapted to abut against an inner peripheral surface of the engaging through hole portion when the shaft is rotated by more than a predetermined rotating angle.

Abstract: A mold for manufacturing a steering shaft formed with inner and outer shafts which are telescopically contractible on impact is disclosed. The mold includes an outer shaft supporting mold portion and an inner shaft supporting mold portion that respectively receive the outer and inner shafts in a telescoped position. A first molten resin injection guide portion formed in the outer shaft supporting mold is located in alignment with a hole formed in the outer shaft and a circumferential groove formed in the inner shaft to enable injection of resin through the hole into the groove. A second molten resin injection guide portion communicates with a first opening formed between the outer and inner shafts to enable injection of resin material into this opening to fix the shafts in concentric alignment with each other.

Abstract: A coupling and sliding section A.sub.3 is formed by an outer shaft A.sub.1 and an inner shaft A.sub.2 of a steering shaft A which is telescopically contractable in the axial direction during receipt of an impact. A resin material 5 is injected between a slid portion 4 of the inner shaft A.sub.2 and a sliding portion 2 of the outer shaft A.sub.1 through an opening 1a of the outer shaft A.sub.1, thereby forming a sliding resin portion 6. In addition, a fixing resin portion 6 is formed in the coupling and sliding section A.sub.3 at an appropriate interval from the sliding resin portion 6.

The energy absorbing member is disposed by being passed through the horizontally crushing through-hole portion, and both sides of the horizontally crushing through-hole portion normally abut against the crushable abutment portions.

Abstract: An apparatus for supporting a tiltable steering shaft includes: a fixed bracket A having a pair of fixing/supporting members A.sub.1 which are connected to each other by means of a U-shaped connecting member 5 so as to be arranged laterally symmetrically at an appropriate distance therebetween; a movable bracket B having a pair of side plates 6 which are arranged in face-to-face relation to each other at an appropriate distance therebetween, the side plates 6 of the movable bracket B being secured to a steering column 2, the movable bracket B being disposed between the fixing/supporting members A1 of the fixed bracket A in such a manner as to be capable of being raised or lowered and of being secured at an appropriate position by means of a tilt-adjusting bar 9. A pair of abutting ends 6a of the side plates 6 of the movable bracket B are capable of abutting against a pair of abutted ends 5a of the connecting member 5 only when an impact load has occurred.

Abstract: A crushing through-hole section is formed at an upper portion of a bracket adapted to move together with a steering column. An energy absorbing body is inserted in the crushing through-hole section. The energy absorbing body has a flat fixed portion and a crushable protruding strip portion continuing therefrom, and is mounted immovably.

Abstract: A device capable of pivotally and axially adjusting by a single operation a steering shaft having a steering wheel. The device includes fixed tilting brackets having descending portions positioned on both sides of a slidable inner cylinder connected to the steering shaft, and a raising/lowering bracket which is attached to the fixed brackets so as to pivotally adjust the steering shaft, and which can ascend and descend together with a steering column. The raising/lowering bracket is attached to the fixed tilting brackets by tightening a screw bar, whereas it can ascend and descend by loosening the screw bar. When the screw bar is tightened, a pressing piece supported by the screw bar pushes the slidable inner cylidner, thereby controlling the movement of the steering shaft in the axial direction of the shaft. On the other hand, when the screw bar is loosened, pressing force is released to permit the steering shaft to move in the axial direction.
