Abstract
An epicyclic step-down gear for an electric parking brake, this step-down gear comprising a drive shaft, at least one step-down stage and a cylinder which forms a screw/nut system with an outer planet gear of this step-down gear. This step-down gear comprises at least one axial force transmission component which is positioned between a bearing ring of the drive shaft and the cylinder so as to transmit axial forces applied via either the bearing ring or the cylinder to either this bearing ring or this cylinder. Such an axial force transmission component prevents the drive shaft from buckling by defining an axial force transmission path which is radially eccentric.
