An air conditioning rotating body (30) has a rotor (10) in a cylindrical shape, the rotor (10) being housed in a casing (50) so as to be freely rotatable, and the air conditioning rotating body (30) is configured to treat air passing through the rotor (10) in an axial direction. A labyrinth seal structure (100) is provided between an outer circumferential portion of the rotor (10) and the casing (50). The labyrinth seal structure (100) includes a first protrusion (23a) protruding in the axial direction of the rotor from the rotor (10) toward the casing (50), and a second protrusion (56a) protruding in the axial direction of the rotor from the casing (50) toward the rotor (10).
