PURPOSE:To reduce the number of rollers and troubles of adjusting by supporting a movable man body by means of a pair of tapers and a pair of presser rollers installed at a pair of supporting shafts provided in parallel to each other in the moving direction and pressing the presser rollers by rotation adjustment at the eccentric shaft parts of the supporting shafts. CONSTITUTION:A movable main body 11 is inserted into a guide frame 1 from one end, and taper rollers 15 are installed to roll each on a taper rail surface 5, then the movable main body 11 is supported to be freely movable along the taper rail surfaces 5, while the shaft center direction of supporting shafts 13 is automatically decided. In this condition, the supporting shafts 13 are rotated, and presser rollers 18 are pressed to presser rail surfaces 8, where they are fixed by set screws 13a in the position. Then the taper rollers 15 are pressed to the taper rail surface 5 by reaction to the pressing force of the presser rollers 18, thereby the movable main body can be correctly positioned because deflection of the supporting shafts 13 in the shaft center direction can be prevented. |
