PURPOSE: To make both shafts of rotation follow the axial center variation of both rolling rolls and to precisely roll rolled stock by supporting bearing parts in the midst of the shafts of rotation connected respectively with upper and lower rolling rolls elastically to a frame part through spring members.

CONSTITUTION: Bearing parts 51,53 enveloping the intermediate part, rotatably, of at least one of an upper shaft 41 of rotation and a lower shaft 45 of rotation in a rolling roll equipment 25 are supported elastically by a frame part 65 through volute spring members 71,83. Even when a distance (a) between the axis center of the upper rolling roll 27 and the axis center of the lower rolling roll 29 varies, the upper shaft 41 of rotation and the lower shaft 45 of rotation can follow this variation within the range of an elastic support of the spring members 71,83. Consequently, this equipment is profitable for performing precise rolling and corrugated flaws can be prevented from being generated on the rolled stock such as steel sheet, etc.
