Claim:
A rotor section for the rotor of a turbomachine, on the outer periphery of which provision is made for rotor blade retaining grooves which extend in the axial direction of the rotor and in which a rotor blade is arranged in each case, having a blade root which corresponds to the rotor blade retaining groove, comprising: a plurality of radially inwardly pointing contact surfaces which are provided in each case on the rotor blades; a plurality of plate-like sealing elements for the guiding of a cooling medium along a rotor surface on an end face wherein the plurality of plate-like sealing elements bear against a contact surface by centrifugal force action and wherein for securing the plurality of sealing elements against displacement in a circumferential direction at least one of the plurality of sealing elements includes an opening provided in the sealing element for accommodating a blocking element, wherein provision is made for a hole, which aligns with the opening, and for a positionally secured blocking element, which fits in the hole and in the opening, and wherein the hole is arranged in the blade root, and in which the blocking element is secured against loss by means of a Z-shaped locking plate, the first end of which lies between sealing element and the end face of the blade root.
