PROBLEM TO BE SOLVED: To provide a multiple rolling mill of high shape control capacity, long bearing service life and high durability. SOLUTION: In the multiple rolling mill 1, reducing roll sets 10 and 10' including work rolls 11 and 11' are arranged symmetrically in the vertical direction across a moving passage of a work 2, and an intermediate roll 12 to press the work roll 11 has a curved surface with the diameter changing in the axial direction, and the shape thereof is asymmetrical with respect to the axis in the width direction (the axial direction) of a barrel, and the intermediate roll is shift-operated by a shift cylinder 24.
