Abstract
Official abstract text for this publication.
A steering device that holds a steering member in such a manner that the steering member is movable between an advanced position where a driver can steer the steering member and a retracted position located closer to the front of a vehicle. The steering device includes: a fixed member attached to a vehicle body; a movable member to which a steering shaft holding the steering member is rotatably attached; and an upper guide mechanism and a lower guide mechanism that linearly guide the movable member with respect to the fixed member. An end on the advancing side of the upper guide mechanism is located further toward the advancing side than an end on the advancing side of the lower guide mechanism in an advancing and retracting direction of the movable member.

The invention claimed is: 1. A steering device that holds a steering member in such a manner that the steering member is movable between an advanced position where a driver is able to steer the steering member and a retracted position located closer to a front of a vehicle, the steering device comprising: a fixed member attached to a vehicle body; a movable member to which a steering shaft holding the steering member is rotatably attached; and an upper guide mechanism and a lower guide mechanism that linearly guide the movable member with respect to the fixed member, wherein an end on an advancing side of the upper guide mechanism is located further toward an advancing side than an end on an advancing side of the lower guide mechanism in an advancing and retracting direction of the movable member, the upper guide mechanism includes an upper fixed guide portion fixed to the fixed member, and an upper movable guide portion disposed on the upper fixed guide portion and fixed to the movable member, the lower guide mechanism includes a lower fixed guide portion fixed to the fixed member, and a lower movable guide portion disposed under the lower fixed guide portion and fixed to the movable member, a length of the upper movable guide portion is greater than a length of the lower movable guide portion, and when in the advanced position, an end on an advancing side of the upper movable guide portion is located further toward the advancing side than an end on an advancing side of the lower movable guide portion. 2. The steering device according to claim 1 , wherein the upper guide mechanism includes upper rolling elements disposed between the upper fixed guide portion and the upper movable guide portion, the lower guide mechanism includes lower rolling elements disposed between the lower fixed guide portion and the lower movable guide portion, and the number of the upper rolling elements is greater than the number of the lower rolling elements. 3. The steering device according to claim 2 , further comprising a trapezoidal cage that holds the upper rolling elements and the lower rolling elements together. 4. The steering device according to claim 1 , wherein an end on an advancing side of an upper part of the movable member to which the upper guide mechanism is attached is located further toward the advancing side than an end on an advancing side of a lower part of the movable member to which the lower guide mechanism is attached.
