PROBLEM TO BE SOLVED: To provide a clearance adjusting method and its device for adjusting a clearance between two rollers 1, 2 by submicron order. SOLUTION: In this device wherein a position of a moving rack 6 holding one roller 2 is adjusted by a wedge type clearance adjusting mechanism 8 comprising a wedge member 10, a wedge member moving device 11 for reciprocating the wedge member, and a driven member 12 moved along a cam face 10a of the wedge member, for adjusting the clearance d between the rollers 1, 2, a piezoelectric actuator 22 capable of varying its length by the application of voltage, is mounted between the driven member and the moving rack 6, and the clearance d between the rollers is finely adjusted by adjusting the voltage applied to the piezoelectric actuator.
