PURPOSE: A steering angle confirming device of a vehicle is provided to exactly detect the steering direction and angle of the vehicle to the turning of the vehicle without malfunctions by pressure sensors including piezo-electric elements and to prevent the reliability reduction for a detected data by malfunctions. CONSTITUTION: A steering angle confirming device of a vehicle is composed of a steering wheel including a central hub(110) of which a lower side is opened, plural spokes(120) radially extended and arranged from the hub, and a rim(130) combined to each front end of the spokes; a fixing shaft(200) of which an end is integrally protruded at the bottom of upper part of the hub and other end is fixed and combined to a steering shaft(140); a pair of supporting units(300,300') of which one side is separated from the inner wall of the hub at a predetermined interval and installed to face each other and other side is fixed to the vehicle; a first pressure sensor fixed and combined to the fixing shaft of the hub to output an electric signal by external pressure; a first band spring(500) 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 a supporting shaft with being wound in a clockwise direction at several times; a second pressure sensor separated from the first pressure sensor at a predetermined interval, and fixed and combined to the fixing shaft to output the 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 supporting shaft 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.
