摘要： A roller screw of the present invention has a screw shaft 1 having a roller rolling surface 1a spirally formed with a lead on an outer surface thereof; a nut 2 having a roller rolling surface 2a spirally formed on an inner surface thereof to face the roller rolling surface 1a of the screw shaft 1; and a plurality of rollers 4 arranged in a rolling path 3 between the roller rolling surface 1a of the screw shaft 1 and the roller rolling surface 2a of the nut 2 and moving around the screw shaft while rotating on rotation axes of the rollers. In this roller screw, each of the rotation axes 4a of the rollers 4 substantially crosses a center line 1b of the screw shaft 1. Since each of the rotation axes 4a of the rollers 4 crosses the center line 1b of the screw shaft 1 (in other words, the rollers 4 arranged in the rolling path 3 are not skewed from the beginning) even when the rolling path 3 has the lead, the roller 4 are allowed to move smoothly.

摘要： The present invention provides a roller screw which bears loads in both directions along the axis of the screw shaft and which is also capable of preventing interference between each roller end surface and roller rolling grooves. Between roller rolling surfaces 1a, 1b of the screw shaft 1 and roller rolling surfaces 2a, 2b, respectively, of the nut 2, there are formed two or more roller rolling paths 3a, 3b, respectively. In one roller rolling path 3a, plural rollers 4a are parallel-arranged, and also in another roller rolling path 3b, plural rollers 4b are parallel-arranged. The rollers 4a arranged in the one roller rolling path 3a bear a load in one direction (1) along the axis of the screw shaft 1, while the rollers 4b arranged in the other roller rolling path 3b bear a load in the opposite direction (2) along the axis of the screw shaft 1.
