ム(dl 。In recent years, rolling mills have been developed in which the work rolls can be shifted in a fine direction in order to eliminate step wear on the rolls and to better control the shape of the rolled material, such as edge drop. In such a conventional shift rolling mill, as shown in FIG. A bracket (el is fixed to the cylinder c+, and a shift cylinder (f) is attached to the bracket (gl), and the rod end of the shift cylinder V+ is attached to the arm (dl).
The arm (dl) is engaged by the telescopic movement of the shift cylinder (fi).

る。(9)はシール部材を示す。As shown in Fig. 1, a cylinder chamber (3α) C3b) is recessed at the axial center position of both ends of the roll parel (2) and has a required depth and diameter from the end face of the roll parel (2).
A roll shaft (4α) (4b) is slidably inserted into each cylinder chamber (3α) C3b) so as to function as a piston, and each roll shaft (4α) C44)
The shaft ends of the shaft boxes (5α) and (5b) are respectively supported by the shaft boxes (5α) and (5b), and the front and rear surfaces of the shaft boxes (5α and 5b) are connected and fixed by a beam (61 (61+2), and the roll shaft (4α)C4b) (= means pressure oil passage (7α) (1) that leads from the shaft end to the cylinder chamber (3α) (3b) (1)
A pressure oil supply device (not shown) is introduced into the pressure oil passage (7α)C7h) via a rotary joint (8α)Cab) at the shaft end of the roll shaft (4cL) (4A). connection). The roll parel (2) and the roll shaft (4α) C4b) are integrated (key α51 (or spline) (=therefore, engaged) so that they can rotate once. (9) indicates a sealing member.
