PURPOSE:To bring roll draft adjusting amounts to be large by supporting a supporting intermediate shaft of an intermediate gear by a 1st arm freely rockable around to center the rotation shaft of a rolling roll and a 2nd arm freely rockable around to center the rotation shaft of a driving side gear. CONSTITUTION:When a rotation shaft is shifted in a radial direction for position adjustment of a rolling roll 2 in a radial direction, a follwer side gear 14 is shifted in a radial direction and a distance between the rotation centers of the gear 14 and a driving side gear 16 is changed. An intermediate gear 15 is shifted in a radial direction by change of the above center-to-center distance. That is, meshing condition of the gear 15 with the gears 14 and 16 is kept to properly transmit a rotating power in a constant condition even if the rotation shaft is shifted in a radial direction. |
