An in-line roller skate is provided which comprises a main chassis (1) having two lateral plates (1a), between which at least two rollers (2, 3, 4, 5) are mounted, and an auxiliary chassis (8) which is of U-shaped profile, which straddles the main chassis and is articulated onto this main chassis. The auxiliary chassis (8) is articulated about two disks (12) which are fixed on the outer faces of the main chassis (1). The disks (12) may have two cylindrical bearing zones (14, 15) of different diameters. The auxiliary chassis (8) has circular cutouts (16), each having diameters corresponding to the diameters of the bearing zones of the disks (12), the smaller diameter (14) being located toward the inside of the auxiliary chassis. This design makes it possible to free the interior of the main chassis for the rollers.
