Provided is a rolling device that is able to accurately detect force in the direction of rolling applied to a work roll chock. The sheet metal rolling device equipped with a vertical pair of work rolls (1, 2) is equipped with: a pair of work roll chocks (5, 6) that hold the work rolls (1, 2); a housing (10) that holds the work roll chocks; and rolling direction force measurement devices (21, 22, 23, 24) that measure the force in the direction of rolling. The rolling direction force measurement devices are equipped with a plurality of load detection devices provided to the housing at the rolling direction incoming side or the rolling direction outgoing side of the work roll chocks, and the plurality of load detection devices are disposed arranged in the direction of pressure decrease in a manner so that when rolling sheet metal, at least two load detection devices are facing the lateral surface of the work roll chocks at all times. At such a time, at least two load detection devices are disposed in a manner so as to sandwich the roll axis center, which is the power point of the force in the direction of rolling in the direction of pressure decrease.
