摘要： A female screw member 6 supported by a movable side bracket 31 includes: a movable side casing 61 provided with a nut container 67 through which a male screw shaft member 54 passes; and a pair of nuts 62 and 63 inserted into the nut container 67 non-rotatably but movably in an axial direction of the male screw shaft member 54 while threadedly engaging with the male screw shaft member 54. The movable side casing 61 includes a wedge member 64 whose tip end 64c is inserted between the nuts 62 and 63. The nuts 62 and 63 are separated from each other when the wedge number 64 is inserted therebetween, and outside surfaces 62c and 63c of female screw portions 62b and 63b of the nuts 62 and 63 come into contact with and get held by a male screw portion 54a of the male screw shaft member 54, thereby eliminating backlash between the female screw portions 62b and 63b and the male screw portion 54a.
