  • Publication number: 20150266499
    Abstract: A steering device includes: a steering shaft and a column jacket that are telescopically adjustable in an axial direction; a lock plate provided with a plurality of holes; a support shaft that extends in a cross direction crossing the axial direction and includes a low-strength portion to be broken when a load acts on the steering shaft and the column jacket; and a lock member that advances to the lock plate to be engaged with one of the holes. The lock member is disengaged from the one of holes when the support shaft is broken in a state in which the lock member is engaged with the one of the holes.

  • Publication number: 20150266496
    Abstract: A steering device includes: a steering shaft and a column jacket that are telescopically adjustable in an axial direction; a lock plate provided with a plurality of holes; a lock mechanism that moves a tooth such that the tooth advances to the lock plate to be engaged with one of the holes, and retreats from the lock plate to be disengaged from the hole. The lock plate includes a bent portion as a stopper at an end portion of the lock plate in the axial direction, and the stopper restricts a movement of an upper jacket relative to a lower jacket in the axial direction by abutting on the lock mechanism in the axial direction when the steering shaft and the column jacket is telescopically adjusted.

  • Patent number: 8967016
    Abstract: A supporting unit of a telescopic adjustment mechanism is placed within an opening hole formed at one end side of an outer jacket and fixed to an outer peripheral surface of an inner jacket. A tip of a screw axle which is movable in an axial direction of a jacket is linked to the supporting unit. The inner jacket placed at an inside of an outer jacket is pressed on an inner peripheral surface of outer jacket by means of a biasing mechanism placed at an opposite side of the opening hole. Thus, positions of the supporting unit and the biasing mechanism along the axial direction of the jacket are substantially coincident with each other and the supporting unit is placed within the outer jacket in the axial direction of the jacket. Consequently, a steering column apparatus can be small-sized in the axial direction of the jacket.

  • Patent number: 8887596
    Abstract: A steering column apparatus has a fixed bracket fixed to a vehicle body and having a pair of long holes extending parallel to each other along a backward-and-forward direction; a movable bracket arranged movably in the backward-and-forward direction; a pair of bolts and a pair of nuts for fixing the movable bracket to a rear portion of the fixed bracket so that the movable bracket can move in the backward-and-forward direction with respect to the fixed bracket; a spring plate having pressing portions for holding the movable bracket at the rear portion of the fixed bracket by pressing the fixed bracket against the movable bracket; a shear pin connecting the fixed bracket and the movable bracket at the rear portion of the fixed bracket; and first and second low friction elements. Upon a secondary collision, the movable bracket smoothly moves toward a vehicle front side together with the spring plate.
