To that end, the linear guide device is provided with a slider main body comprising a slider which engages in relative movement in the longitudinal direction of a guide rail and which has multiple rotating element raceway grooves that are opposite of multiple rotating element raceway grooves formed on the guide rail. The center of the surface of the rotating element raceway groove (4, 6) is formed with a first circular arc (8), a lateral portion of the surface of the rotating element raceway groove (4, 6) which is adjacent to the groove surface center is formed with a second circular arc (9) having a greater radius of curvature than that of the first circular arc (8), and at the connection (10) between the first circular arc portion (8) and the second circular arc portion (9) is a tangent line T which is common to both.
