Rotor blades have feet engaged in axial grooves in a rotor disc and foot plates on the blades form with the surface of the rotor disc, axially and circumferentially extending intermediate spaces. Between sections of the blades and the rotor disc, overlaps of structural parts are developed at the intermediate spaces, by which the blades are fixed axially in the grooves in one direction. The overlaps of the structural parts can be formed between profiled or ground contours surfaces of the blade feet and profiled or broached contours surfaces of the rotor disc.
