Claims

[Scope of utility model registration request]

A guide rail having roller rolling grooves in the axial direction on both sides, and a roller rolling groove movably spanning the guide rail in the axial direction and facing the roller rolling groove on the inside and parallel to the roller rolling groove on the outside. The slider body includes a slider body provided with a roller circulation path, and a curved roller switching path that communicates the roller circulation path with the inclined rolling path formed by the roller rolling grooves formed opposite to each other. A roller type linear comprising end caps connected to both ends, and a large number of rollers that are inserted into an endless roller circulation path consisting of the inclined rolling path, diversion path, and circulation path and roll as the slider moves. In the guide device, the roller endless circulation path is formed in a double row of upper and lower rows, and the roller switching path is provided with a guide surface that changes the inclination of the roller rotation axis by about 45 degrees while guiding and changing the traveling direction of the rollers in an arc shape. A roller-type linear guide device characterized by forming.
