Steering apparatus for vehicle
First Claim
1. A steering apparatus for a vehicle, adjusting a position of a steering wheel in a longitudinal direction of a vehicle body, the steering apparatus comprising:
- a main tube supported by the vehicle body and having a tubular shape, the main tube including an opening portion being closed in an axial direction of the main tube and extending in the axial direction;
a telescopic tube supported by the main tube to be slidable within the main tube;
a connecting member having a tubular shape and being movable within the opening portion along the axial direction of the main tube, the connecting member possessing a first end attached to the telescopic tube and a second end;
a screw shaft and a nut threadingly engaging the screw shaft, at least a portion of the nut being housed within the connecting member;
the second end of the connecting member being positioned farther away from the telescopic tube in a direction orthogonal to the axial direction than a portion of the screw shaft closest to the telescopic tube;
a drive source configured to rotate the screw shaft and thereby move the nut, the connecting member and the telescopic tube in the axial direction; and
first and second lock portions positioned on opposite sides of the opening portion of the main tube along the axial direction, the connecting member being contactable with the first and second lock portions to prevent the nut from directly contacting the first and second lock portions.

7. An apparatus for adjusting a steering wheel of a vehicle comprising:
-
a main tube fixable to the vehicle and extending along an axial direction, the main tube surrounding a hollow inner space and possessing an open axial end; a hole formed in the main tube to provide access to the hollow inner space of the main tube; a telescopic tube slidably supported within the main tube so that the telescopic tube is movable along the axial direction, the telescopic tube protruding from the open axial end of the main tube; a connector attached to the telescopic tube and extending in a radial direction through the hole formed in the main tube; a threaded shaft extending along the axial direction and a nut threadingly engaged to the threaded shaft, at least a portion of the nut being housed within the connector, the threaded shaft passing through both the nut and the connector; a motor configured to rotate the threaded shaft and thereby move the nut, the connector and the telescopic tube along the axial direction; and first and second stops positioned on opposite sides of the hole in the main tube to contact the connector when the telescopic tube moves into a fully-extended position or a fully-retracted position. - View Dependent Claims (8)
