PROBLEM TO BE SOLVED: To provide a compact and space-saved rolling mill without providing any universal spindle between a rolling mill body and a driving device regardlessly of the employment of double support type easily adaptable to have multiple calibers. SOLUTION: The rolling mill is composed of: a rolling mill body: a gear stand 3 which transmits the driving force of a motor to the rolling mill body and has a first arm 31 to support a first output shaft 33 and a second arm 34 to support a second output shaft 36; an arm turning means 4 to allow the first output shaft 33 and the second output shaft 36 to be brought closer to each other and separate from each other by synchronously moving the first arm 31 with a main input shaft 32 as a turning center and the second arm 34 with a sub-input shaft 35 as a turning center, respectively; and a flexible coupling 5 which permits the misalignment between the shafts to be coupled with each other, and couples the first output shaft 33, a rotary shaft 22a of an upper reduction roll 22 and the second output shaft 36 with a rotary shaft 24a of a lower reduction roll 24.
