ROLLING MOTION GUIDE

摘要

A rolling motion guide provided with a track rail (2) provided with load rolling body rolling portions (41, 51, 61) on the top surface and both side surfaces thereof, a moving block (3) having a horizontal section (8) and sleeve sections (9, 9), on each of which load rolling body rolling portions (42, 52, 62) are provided to correspond to the load rolling body rolling portions of the track rail (2), and a multiplicity of rolling bodies (4, 5, 6) rollingly interposed between the load rolling body rolling portions of the track rail and the load rolling body rolling portions of the moving block, wherein contact angle forming lines (S2, S3) are inclined downward toward the track rail (2), the lines (S2, S3) being defined by connecting points of contact between the rolling bodies (5, 6) disposed on the respective sides of the track rail (2) and a pair of the load rolling body rolling portions (51, 52; 61, 62), which interpose therebetween the rolling bodies, in a state where a compressive load acts between the moving block (3) and the track rail (2).
