PURPOSE: A right and left rotation angle adjustment device of a horn for a vehicle is provided to reduce an accident caused by contact with a person or cattle in front of the vehicle by making the horn automatically rotate according to the rotation angle of a steering wheel. CONSTITUTION: A right and left rotation angle adjustment device(100) of a horn(101) for a vehicle is fixed to the front of a vehicle body, to warn an object or a person in front of the vehicle of peripheral circumstances. When the vehicle travels on a curved road, the right and left rotation angle adjustment device of the horn senses the rotation angle of a steering wheel from a steering wheel-angular velocity sensor(121) and adjusts the rotation angle of the horn, to make the rotation direction of wheels and the direction of a sound produced from the horn coincide. The right and left rotation angle adjustment device of the horn comprises a horn-mounting member(103) rotating right and left around a hinge point of the center part; rack gears(107,109) fastened to the side parts of the lower end of the horn-mounting member; pinion gears(111,111') engaging with the rack gears; motors(113,113') operating each pinion gear; the steering wheel-angular velocity-sensing part sensing the rotation angle of the steering wheel of the rotating vehicle; and an ECU(Electronic Control Unit,119) receiving a signal transmitted from the steering wheel-angular velocity-sensing part and driving the motors in a right or reverse direction if the rotation angle of the steering wheel is inclined.
