    The present invention relates to a steer-by-wire type steering device and, more specifically, to a steer-by-wire type steering device capable of preventing rotation of a steering shaft when a driver generates rotation torque in excess of the reaction torque in the steering shaft. According to embodiments of the present invention, the steer-by-wire type steering device includes: a first member connected to one side of the steering shaft or a motor shaft and having a fixing groove of an axial direction on the outer circumference of one end; a second member connected to the outside of the first member by having a fixing protrusion corresponding to the fixing groove and formed in the axial direction, wherein the second member also has a first support groove installed at an interval in a circumferential direction on the surface of one end and is connected to the outside of the first member; a third member connected to the remaining one side of the steering shaft or the motor shaft and having a second support groove formed at a position corresponding to the first support groove; a ball member supported and inserted into the first support groove and the second support groove; and a rotation preventing member formed in a ring shape fixed to a housing including the steering shaft and having a hanging groove of the axial direction on the inner circumference, wherein the rotation preventing member is connected to the outer circumferences of the second member and the third member.
