Abstract

PURPOSE: To certainly prevent deflection by arranging, on a driven member, a guide roller which engages with the concaved grooves on both sides of a female member, in a rectilinear movement apparatus in the engagement of the male element and the female element which has partial screw groove holes in the concaved- grooved center region having a circular section.
CONSTITUTION: A rectilinear movement apparatus is equipped with a female screw element 1 which has the center region 2 where partial screw groove holes 3 are formed in the direction of axis line, and said member 1 is installed in the direction up and down on the vertical wall surface of a structure. With the female screw member 1, the male screw member 9 having a group of rollers 10 which are supported rotatably on the outer periphery of a cylinder is engaged. The male part 9 is supported rotatably onto the cage body 12 through bearings 13 and 14, and revolved through a chain and a sprocket 15 etc. through the revolution of a motor 17. In the apparatus described above, the concaved groove side part 5 is formed on each side of the female screw member 1, and the guide roller 24 in the form of engagement with the concaved groove side part 5 is installed onto the cage body 12 by means of a supporting arm 23.
