PURPOSE: A steering angle confirming device of a vehicle is provided to easily and reliably execute the angle and direction changes of a steering wheel by a plurality of gears and pressure sensors comprising 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 housing(300) through which a steering shaft(200) mounted to the lower of a steering wheel rotatively passes, fixed and installed to a vehicle body; a first pressure sensor fixed and combined to the steering shaft in the housing to output an electric signal by external pressure; a first band spring of which an end is fixed and combined to the outer periphery of the first pressure sensor and other end is fixed to the inside of the housing with being wound in a clockwise direction at several times; a second pressure sensor(600) separated from the first pressure sensor at a predetermined interval and fixed and combined to the steering shaft in the housing to output an electric signal by external pressure; a second band spring(700) of which an end is fixed and combined to the outer periphery of the second pressure sensor and other end is fixed to the inside of the housing with being wound in a counter clockwise direction at several times; and a microcomputer for computing rotational direction and angle of the steering wheel to the electric signal output from the first and second pressure sensors.
