PURPOSE: A steering angle confirming device of a vehicle is provided to simply and reliably execute angle and direction changes of a steering wheel by using plural gears and pressure sensors including piezo-electric elements to detect left and right rotations and rotational angle of the steering wheel. CONSTITUTION: A steering angle confirming device of a vehicle is composed of a driving gear(200) integrally fixed and combined to a steering shaft(110) mounted to the lower of a steering wheel; a driven gear(300) installed to a vehicle body to rotate with engaging with the driving gear and formed with a plurality of tooth-gears(300a) around the outer periphery at regular intervals; at least one pressure sensor(400,400') mounted to the tooth-gears of the driven gear to output an electric signal to pressure generated when the driving and driven gears are engaged and rotated; and a microcomputer(500) for computing rotational direction and angle of the steering wheel by the electric signal output from the pressure sensors.
