Abstract: Force transferring elements are disclosed which include a metal or plastic hub deep drawn or elongated with a flange extending therefrom and functioning as a force transferring element. The hub and flange may be of one piece with the flange having blades extending outwardly from the hub, the hub around its circumference being provided with a plurality of indented portions or corrugations to provide a spring action for engagement with a shaft. In another form of the invention two similar pieces are utilized each with a deep drawn or elongated hub and having outer rims which together receive a V-belt or the like. The elements may be connected to a shaft for input to the shaft, or may be carried on the shaft as energy converting or driving members.
