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： A motion guide device is able to damp a moving block from vibrating in a direction perpendicular to an axis of a raceway rail. A damping plate with a surface facing a surface of a raceway is provided at a moving block body. The surface of the damping plate is set to be in contact with the raceway rail or is set such that a gap between its surface of the raceway rail is as close to zero as possible. When vibration occurs from the raceway rail or the moving block, the surface of the raceway rail and the surface of the damping plate come into contact with each other. This brings about change in a spring constant of the motion guide device in the direction perpendicular to the axis of the raceway.

摘要： A track rail is composed of a pair of rail members in which rolling contact surfaces for rolling bodies are formed, respectively, and a rail housing equipped with a pair of rail mounting grooves in which those rail members are fitted, respectively. Each of the rail members is fixed within a corresponding one of the rail mounting grooves via an adhesive layer. A reference projection, formed on a bottom of one of the pair of the rail mounting grooves, is in contact with a corresponding one of the rail members without the intermediary of the adhesive layer. The rail member fitted in the one of the rail mounting grooves is adhesively fixed in a state of being abutted against the reference projection. The rail member fitted in the other rail mounting groove is adhesively fixed at a predetermined distance from the reference projection.
