A gear mechanism or motor includes a shaft, and output rotary bodies which are in engagement therewith. The bodies interact with the shaft in the radial direction, by bearing against the shaft, and interact in the axial direction of the shaft with an upper guideway body which can move in the axial direction and is loaded toward the bodies. An interaction region of the shaft has a circular cross section. A guideway of the guideway body is structured in terms of its height over its periphery.
