<p>A husking-roll driving device where are provided a first belt-clutch mechanism (15) switching power transmission to a first large-diameter pulley (9), and, at the same time, a second belt clutch mechanism (26) switching power transmission to a second large-diameter pulley (20), and
a first and a second belt clutch mechanism (15,26) are provided with a first and a second arm members (16,27), tension clutch pulleys installed at point portions of these arm members, and actuators which rotate a first and a second arm members in such a way that a position at which a first no-end belt (13) is wound on the first large-diameter pulley (9) is switched to a position at which winding is avoided, and, at the same time, a position at which a second no-end belt (24) is wound on a second large-diameter pulley (20) is switched to a position at which winding is avoided.
