Constitution Guide carriage rail 12,12A between earth stationary panel 4Making interval the top and bottom in side wall 14 of channel A side, the complete penetration aperture 15It forms. Ardently projection of the destal of spindle as a beam 13Stopping piece 20 is provided perpendicularly in the Tip of rod 19. Stopping pieceAs for 20 with only fixed direction directing the complete penetration aperture 15 to outside the channelIt passes, after passing it stops passing through from the complete penetration aperture 15. ProjectionThe tightening nut 22 which in male screw section 22 of rod 19 the spiral shellfish is adjustedWhen it fastens, through elastic washer 21, stopping piece 20 and tightening natsuto 22 to overpower side wall 14, as for spindle 13 the guideIt is concatenated to carriage rail 12,12A. As for bearing shelf 24 stopping pieceThe Interpolation of 20 deviation from it makes easy.
