Abstract
In a steer-by-wire steering apparatus according to embodiments of the present invention, a structure for preventing rotation of a sliding bar in order to allow the sliding bar to slide in the axial direction by the torque of a motor or a structure for determining a position to which the sliding bar moves can be more simply implemented, whereby the number of components can be reduced, the assembly process can be simplified, and the cost can be significantly reduced.

1-18. (canceled)
A steer-by-wire steering device, comprising:
- a sliding bar provided to be axially slidable in a housing;
- a motor connected with the sliding bar by a gear box;
- the gear box including a nut pulley configured to be rotatable in conjunction with linear movement of the sliding bar;
- and
- a sensor configured to detect rotation information from the gear box and detect a linear movement position of the sliding bar based on the rotation information,
- wherein the sensor includes a first gear configured to be rotatable in conjunction with the nut pulley and is configured to detect the rotation information from the first gear to determine the linear movement position of the sliding bar.

A steer-by-wire steering device, comprising:
- a sliding bar provided to be axially slidable in a housing;
- a motor connected with the sliding bar by a gear box;
- the gear box including a nut pulley configured to be rotatable in conjunction with linear movement of the sliding bar;
- an anti-rotation member formed with a hollow, circumferentially supported by the sliding bar, and coupled to an inner circumferential surface of the housing;
- and
- a sensor configured to detect rotation information from the gear box and detect a linear movement position of the sliding bar based on the rotation information,
- wherein the sensor includes two first gears configured to be rotatable in conjunction with the nut pulley and is configured to detect an absolute angle of a rotation of a ball nut in the nut pulley based on first rotation information of one of the two first gears and second rotation information of the other of the two first gears.
