The present invention discloses a tire chuck apparatus (15) for holding a tire (13) having a tire bead (27). The apparatus comprises: a gripping mechanism with at least two gripping members movable (36) in tire radial direction from a retracted position to an extended position for pressing against the inner side of the bead portion of the tire, thereby holding the tire; gripping rollers (36) as the gripping members adapted to be rotatable around an axis substantially parallel to a central axis of the tire; and a rotation drive mechanism (63) for rotating the tire around the central axis of the tire. According to this apparatus, even if the center of the tire and the center of the chuck are out of alignment with each other, by rotating the gripping rollers so as to rotate the tire, the tire is shifted so that the center thereof is aligned with the center of the chuck apparatus, thus reducing mispositioning. <IMAGE> |
