A shimmy reducing device of a knuckle for automotive suspension is provided to actively control back and forth directions of knuckles and tie rod fixed points in order to minimize the right and left movement of rack bars, thereby reducing the vibration of a steering in a rotation direction. A shimmy reducing device of a knuckle for automotive suspension comprises: an actuating unit to move knuckles(100) and tie rod fixed points in a shimmy region to a X-coordinate in front of a vehicle. The actuating unit consists of: a sensor(11) to detect the rotation of a tire in order to measure the shimmy region; an operating unit(13) to allow the fixed points to be moved back and forth; and a controller(12) to control the operating unit. The operating unit is composed of: a driving motor rotating according to the control signal of the controller; and an actuator linearly operated by the driving motor.
