The present invention relates to a technique capable of generating a steering reaction while minimizing a steering difference when a main motor for forming a steering reaction is failed. According to the present invention, disclosed is a steering reaction device of a steer-by-wire system, comprising: a first motor and a second motor providing a rotational force; a planetary gear apparatus selectively inputted with the rotational force from the first motor or the second motor, and generating the steering reaction by outputting the rotational force to a steering wheel; a braking means for selectively braking a rotational element of the planetary gear apparatus connected with the first motor and the second motor; and a controller for providing a signal to operate or not to operate the braking means when the first motor or the second motor fails.
