摘要： The present invention provides a roller screw capable of circulating rollers smoothly.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： A motion guide device having a novel scoop section structure whose scoop section is not likely to break even if a movement member is moved at high speed. A scoop section (22) of a movement block (12) scoops balls (13) that roll in a ball rolling groove (11a) of a raceway rail (11) and introduces them into no-load ball return paths (17, 20). The scoop section (22) is formed in a Gothic arch groove shape in which the scoop section (22) is in two-point contact with a ball (13). In a cross-section orthogonal to the advance direction of the balls (13), an angle (contact angle α) formed by a line L1 that connects a point P at which the scoop section (22) and a ball (13) are in contact and the center C of the ball (13) and a line L2 that connects the center of the ball (13) and a bottom (22a) of the Gothic arch groove-shaped scoop section (22) exceeds 30 degrees and is not more than an angle γ formed by a line L3 that connects the center C of the ball (13) rolling in the ball rolling groove (11a) of the raceway rail (11) and an edge (35) of the ball rolling groove (11a) of the raceway rail (11) and the line L2 that connects the center C of the ball (13) and the bottom of the ball rolling groove (11a).
