A steer by wire type steering apparatus comprising:
- a steering shaft coupled to a steering wheel to rotate;
- a steering sensor for detecting a rotation direction of the steering shaft;
- an electronic controller for operating a steering motor in forward and reverse directions according to the rotation direction sensed by the steering sensor;
- a first pulley provided on a shaft of the steering motor;
- a second pulley provided on the steering shaft;
- a driving belt coupled to the first pulley and the second pulley;
- and
- a belt support member that rotationally supports one side of the driving belt and is coupled to a reduction gear housing,
- wherein the belt support member comprises:
- a rotating member supported on one side of the driving belt and having a cylindrical shape;
- a bearing supported on an inner circumferential surface of the rotating member;
- a support shaft coupled to an inner side of the bearing;
- and
- a fixing member coupled to the reduction gear housing through the support shaft,
- wherein the support shaft comprises:
- a bearing coupling portion to which the bearing is coupled to an outer circumferential surface;
- and
- an eccentric support portion having a central axis biased toward one side in a radial direction from a central axis of the bearing coupling portion and having an outer diameter different from an outer diameter of the bearing coupling portion, and
- wherein the belt support member comprises a support member that supports one side of the eccentric support portion and supports the rotating member toward the driving belt.
