An apparatus for generating warning vibrations of a steering wheel comprises: a reservoir which is placed inside a steering wheel and filled with a non-conductive fluid; a connection tube which is connected to the reservoir and forms a flow path for the non-conductive fluid; an actuator which is arranged inside the steering wheel, is connected to the connection tube, and is configured to vibrate based on the inflow and outflow of the non-conductive fluid from the connecting tube; a positive electrode and a negative electrode which are arranged on both sides of the reservoir; a high-voltage power supplier which is configured to provide voltage to be applied to the positive electrode and the negative electrode; and a vibration generating controller which is configured to selectively apply output voltage from the high-voltage power supplier to the positive electrode and the negative electrode. The apparatus for generating warning vibrations of a steering wheel can create warning vibrations so that a driver can feel the vibration more gently but definitely.
