Abstract
Abstract A push element for a transmission belt comprising an endless carrier packed with a plurality of such elements to run on Vee-pulleys with variably spaced side plates. The surface of the element which comes into contact with the inside surface of the carrier is of convex shape to minimize wear resulting from improper alignment of the elements in use.
