ABSTRACT:
An indicator unit which can be fixed on a tilted steering wheel for indicating the turn condition of the wheel. The indicator mainly includes a base member secured to the wheel, a bias-weighted member pivotally mounted on the base member to maintain itself in an upright position during rotation of the base member with that wheel, a ball-shaped member laid between the base member and the bias-weighted member, constrained by a spiral groove and a radial slot separately furnished on the two members so that the relative rotation between the two members causes the ball-shaped member to move along the radial slot of the bias-weighted member, and a pointed member pivoted on the bias-weighted member and having a curved slot which crosses the ball-shaped member so as to convert the radial movement of the ball-shaped member into swing motion of the pointer member, thus indicating the corresponding turning direction of the car wheel relative to the turning of the steering wheel.
