Provided is a vehicle steering column. A lower column has an open area, an axial slot provided in a central portion of the open area, a connecting portion connecting portions of the lower column located on both sides of the open area, a cut portion corresponding to the slot and provided on one side of the connecting portion, and a pair of protruding opposite end portions. A hinge pin is fitted into the opposite end portions of the lower column. An upper column is fitted into the lower column. A telescopic fixing plate of the upper column is provided in a location corresponding to the slot, and has a plurality of catch recesses spaced apart from each other. A telescopic catch member is located in the cut portion between the opposite end portions to be rotatably supported by the hinge pin, and has a catch protrusion engaging with the catch recesses.

The present disclosure relates to a steering system comprising a rotatable steering wheel hub; a steering system support column including an off-axis section and an aligned section that are connected by a connection portion. The steering wheel hub is rotatably mounted on the aligned section, while the off-axis section is axially spaced from the steering wheel hub. The steering system comprises a torque feedback device including an electric machine having a rotor and a stator, the rotor being attached to the steering wheel hub so as to be rotatable with the steering wheel hub about the axis of rotation, and the stator being non-rotatably fixed to the aligned section of the steering system support column.

In a steering device according to an aspect of the present disclosure, a lock mechanism includes a rod, a drive cam, and a driven cam. The lock mechanism causes paired side plate portions to approach each other in a right-left direction with a drive base and a driven base being separated from each other in the right-left direction as a cam portion slides on a cam follower portion toward a first side in a circumferential direction and causes the paired side plate portions to be separated from each other in the right-left direction with the drive base and the driven base approaching from each other in the right-left direction as the cam portion slides on the cam follower portion toward a second side in the circumferential direction. A first portion from among the cam portion and the cam follower portion includes a first top portion that comes into contact with a second portion from among the cam portion and the cam follower portion, and a first clearance portion that extends to become farther from the second portion in the right-left direction from the first top portion toward an outer side in a radial direction intersecting a second axis.

A steering device according to an aspect of the present disclosure includes a column unit, a front bracket, a rear bracket, and a lock mechanism. The lock mechanism includes a rod supported by the column unit so as to be movable in a vertical direction in tilt guide holes in an unlocked state, and an operation portion that is fixed to a first side end portion of a rod in a right-left direction and that is used to operate of the rod. The first through-hole includes a first straight portion and a first tapered portion. The second through-hole includes a second straight portion and a second tapered portion.

Disclosed is a steering column for a vehicle. A steering column for a vehicle according to an embodiment of the present invention includes a housing provided in a vehicle and having an opening formed at one side thereof, a hollow shaft installed in the housing and configured to be movable in an axial direction through the opening of the housing, a roller having an outer peripheral surface configured to press an outer peripheral portion of the hollow shaft, an actuator configured to provide driving power for rotating the roller, and a first shaft configured to rotate relative to the hollow shaft and installed in the hollow shaft so as to be movable together with the hollow shaft, in which when the roller rotates, the hollow shaft and the first shaft are moved by a frictional force generated between the hollow shaft and the roller.
