A steer by wire type steering apparatus, comprising:
- a sun gear coupled to a steering shaft connected to a steering wheel operated by a driver and rotating in interlocking motion;
- a planetary gear externally coupled to the sun gear;
- a ring gear to which the planetary gear is internally coupled, two first support protrusions are provided at adjacent positions in a circumferential direction from one end of the ring gear of an axial direction, and at least one of the first support protrusions is coupled to and fixed to an inner circumferential surface of a gear housing;
- and
- a carrier to which a rotation shaft of the planetary gear is coupled and provided with a second support protrusion supported by at least one of the first support protrusions on an outer circumferential side.
