Abstract

The present embodiments relate to a steer-by-wire-type steering apparatus. The present embodiments may provide a steer-by-wire-type steering apparatus including: a locking member coupled to a shaft of a reaction motor and having locking teeth formed on an outer circumferential surface thereof; a pair of rotation-preventing members pivotally coupled by hinge axes at one ends thereof and having locking protrusions, which are supported by the locking teeth, formed at the opposite ends thereof; a cam rotatably coupled to a shaft of a driving motor so as to pivot the rotation-preventing members and having one side provided with one of a fixing recess and a fixing member inserted into the fixing recess; and a cam holder having one side, which faces the one side of the cam, provided with the other of the fixing recess and the fixing member.

Dependent claims

A steer-by-wire-type steering apparatus comprising:

a locking member coupled to a shaft of a reaction motor and having locking teeth formed on an outer circumferential surface thereof;
a pair of rotation-preventing members pivotably coupled to respective hinge axes at respective first ends thereof and having locking protrusions, which engageably lock with the locking teeth, the locking protrusions formed at the respective second ends of the rotation-preventing members;
a cam rotatably coupled to a shaft of a driving motor so as to pivot the rotation-preventing members;
and
a cam holder having one side, which faces the one side of the cam,
wherein one side of the cam is provided with one of a first fixing recess and a fixing extension, and the one side of the cam holder provided with the remaining one of the first fixing recess and the fixing extension, and
wherein the fixing extension is located in the first fixing recess.
