Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a feeder that a linear shaft and a rolling part are always covered with the lubricant of a fixed quantity in addition to being the higher reproducibility, higher fidelity and also higher thrust force by improving the feeding accuracy and securing the smooth linear motion. SOLUTION: To achieve this purpose, a plurality of rollers (3) touching obliquely to the circumference face (2) of a columned linear shaft (1) is attached on a moving block (4) and this moving block (4) is fitted so that the above plural rollers (3) surround the above linear shaft (1). In the feed gear without screw that makes the above moving block (4) move in a straight line along the linear shaft (4) by rotating the above linear shaft (1), it is the feed gear without screw characterized so that the above rollers (3) enlarge both ends more larger than the diameter of the center of the rollers (3) and then the above linear shaft (1) and the above rollers (3) contact with 2 points.
