Abstract

PURPOSE: To surely remove the backlash between screws, by sectioning a part or all of female screw in axial direction into a plurality toward radial direction, and tightening it radially to the male screw with a common ring spring.
CONSTITUTION: Female screw parts 26-1, 26-2 sectioned radially are tightened externally through the radial force to the male screw 23 by ring springs 28a, 28b having notch 29. Thus, the female screws 26-1, 26-2 are unifiedly held so that they are screwed to the male screw 23. Further, the backlash between the male screw 23 and the female screws 26-1, 26-2, that is, a loose between the screws 23a, 26a is removed. Thus, even with wear at the screws 23a and 26a, no backlash is produced.
