A mechanism for use in a reduction planetary gearing with an eccentric output gear, comprises a plate (22) with four apertures receiving axially extending projections in diametrically opposed pairs (24a,24b,25a,25b) on the input and output coupling members (21,23). The projections (24a,24b,25a,25b) are radially movable in the apertures which may open into the periphery of the plate. <IMAGE> |
