A sealing device for sealing the space between two parts (3, 4) rotating relative to one another, has a sealing element (1, 2) which is arranged between the parts and which surrounds the inner part (3). The sealing element (1, 2) is in the form of a part which surrounds the inner part (3) in the form of a closed ring and which is arranged to be movable in the radial direction relative to the outer part (4). In particular, the sealing element (1, 2) comprises a brush seal (2) and a seal carrier (1) for holding the brush seal (2) on the outer part (4), the seal carrier (1) being arranged to be movable in the radial direction. The carrier abuts element 9 for axial location and has slide elements 5 that extend from it and engage between guide elements 6 on part 4. The guide elements give circumferential location and allow radial sliding. The sealing device is used to seal spaces between parts of a jet propulsion unit, especially between the rotor and guide blades of the jet propulsion unit.
