A labyrinth disk includes a main stiffener placed in the middle of the rim immediately below labyrinth elements. Attachment elements are preferably in the form of a bayonet attachment system using teeth fixed on the labyrinth disk crown and teeth fixed on the rotor. Attachment by bolting may optionally be used. The disk may be utilized with turbojets, on the cooling circuit, on the upstream side of the high pressure turbine.

[ We claim:] [1.] A labyrinth disk for a turbomachine rotor having a rotor disk with a main stiffener, comprising:a main rim,a labyrinth built into the rim,a crown placed in an outer extension of the rim supported on an upstream surface of the rotor disk, said crown comprising the upper part of the rim, being at least partially elongated in a radial direction and being at least partially convexly shaped, a downstream surface of said crown being located in substantially the same axial position as a downstream end of the main stiffener, andan attachment attaching the labyrinth onto the rotor disk,wherein said attachment comprises a radial main stiffener built into the rim.
