The invention intends to always maintain a distance between a hydrostatic pressure bearing and a roll even in a transient state before and after the start of rolling, thereby sufficiently and surely preventing damage of those components upon contact with each other, and to prevent a lowering of yield. In a plate rolling mill comprising upper and lower work rolls, and hydrostatic pressure bearings for supporting barrel portions of idler rolls in a non-contact manner with fluid pressure substantially along the horizontal direction, the idler rolls supporting the work rolls substantially along the horizontal direction, gap restraining rolls are provided to prevent gaps between the hydrostatic pressure bearings and the idler rolls from becoming lower than a predetermined value.
