PURPOSE: A steering-auxiliary mechanism equipped with a wheel-steering angle indicator is provided to easily and safely perform steering wheel-operation by installing a wheel-steering angle indicator to a steering-auxiliary mechanism. CONSTITUTION: A steering-auxiliary mechanism equipped with a wheel-steering angle indicator comprises a case(10) fixed to a steering wheel; a central shaft(30) housed in the case; a handle(20) supported to the central shaft; a transparent protective plate(21) installed on the handle; a cylindrical scale plate(50) with a notch mark indicating rotation of wheels; a moving plate housed in the scale plate, with having gear teeth formed on the inner wall and a rotational frequency-indicating hand pictured on the top; an angle-indicating hand disposed between the scale plate and the moving plate and fixed at the end portion of the central shaft; a first gear disposed inside the moving plate and fixed to the central shaft; a second gear transmitting rotation of the first gear to a third gear engaged with the teeth formed on the inner walls of the second gear and the moving plate; and a base plate supporting the second gear and the third gear and fixing the scale plate. The base plate is supported to the central shaft, to freely rotate, with a weight at an end. The steering-auxiliary mechanism is simply assembled and disassembled and therefore, the expense is cut down.
