[Scope of utility model registration request] In a roller leveler having a plurality of upper and lower work rolls arranged to sandwich a pass line and upper and lower backing rolls that back up the upper and lower work rolls, the upper and lower backing rolls are respectively supported by upper and lower shaft boxes to form an upper and lower backing roll unit. The upper and lower restraint roll units are respectively provided with upper and lower wheels, and the upper restraint roll unit is provided with an upper restraint via an upper guide rail in a direction perpendicular to the pass line that engages from the lower side of the upper wheels. It is equipped with a lifting device that supports the roll unit so that it can be raised and lowered, and on the lower support roll unit side, a guide rail for pulling out the lower support roll unit from the working position is provided at a position corresponding to the lower wheels in a direction perpendicular to the pass line. A roll changing device for a roller leveler, further comprising a device for raising and lowering the upper and lower work rolls.
