Abstract
An apparatus for driving a pair of balancers disposed on both sides of an engine, parallel to the crankshaft, and driven rotationally in opposite directions at a speed twice the rotating speed of the crankshaft by the motive power of the crankshaft. An elongate endless member engages rotors, one fitted on each balancer, on a cam shaft, and on the crankshaft. The internal side of the endless member engages with the rotor on one of the balancers. The external side of the endless member engages with the rotor on the other balancer to drive the two balancers reversely to each other without employing any particular reversing mechanism.
