PROBLEM TO BE SOLVED: To provide a roll stand for rolling a cast slab in continuous casting equipment, which can be constructed by one expansion means for one movement-side roll, and can be arranged at small interval of strands, and in which a plurality of slab rolling amounts can be set in a width range and also at high precision even if it has a low rigidity structurally or thermal expansion caused by a temperature change is generated. SOLUTION: In the roll stand for rolling a cast slab in continuous casting equipment, spacers 13 freely rotatable around a rotary shaft line C1 are interposed between a standard side bearing box 10 freely rotatably supporting a standard side roll 5 and a movable side bearing box 11 freely rotatably supporting a movable side roll 6. The spacers 13 are formed in such a manner that the distance between the confronted sides or confronted apexes in the cross-section orthogonal to the rotary shaft line C1 is changed, the rotary angle of the spacers 13 is changed and, via the confronted sides or apexes, and the standard side bearing box 10 and the movable side bearing box 11 are press-contacted each other, thus the gap between the rolls upon the rolling of the cast slab can be adjustably composed.
