1. A rolling mill comprising:
a work roll;
bearings that are provided on an operation side and a drive side of the work roll, and support the work roll;
an operation side thrust force supporting device that is provided on the operation side of the work roll, and applies forces in both directions of the operation side and the drive side to the bearing on the operation side; and
a drive side thrust force supporting device that is provided on the drive side of the work roll, and applies forces in both directions of the operation side and the drive side to the bearing on the drive side,
the operation side thrust force supporting device and the drive side thrust force supporting device each applying a force in a same direction to the bearing when the work roll is not shifted in an axial direction at least during rolling.
