ABSTRACT:
A wheel balancer comprising a pair of shafts for supporting a rotary shaft for rotatably mounting a wheel having an amount of unbalance to be measured is disclosed. The supporting shafts are located on a circle having a center which is coincided with a movable instantaneous center of vibration of the wheel and held by a pair of spring members such that the supporting shafts are movable in a direction of a tangent touching the above mentioned circle. The amount of unbalance of the wheel is converted into an electrical signal which is supplied through a calculation circuit to a comparison circuit which can detect the position of the instantaneous center of vibration by means of an indicating means movable in proportional to the amount of movement of the instantaneous center of vibration of the wheel.
