<p>Provided is a linear guide device in which, even when an offset load is applied to rollers rolling in a load rolling path, the offset load can be effectively reduced and the movement of a slider relative to a raceway rail can be smoothened, and wear of the rollers can be prevented as far as possible. In the linear guide device, a bearing race with a load rolling surface on which rollers roll is provided, the slider is provided with a reception groove where the bearing race is fitted at a position opposed to a raceway rail-side rolling surface. The bearing race and the reception groove are formed in a substantially semi-circular cross-sectional configuration in a direction orthogonal to the rolling direction of the rollers. The bearing race is structured so as to be oscillatable in the reception groove, with an outer peripheral surface of the bearing race being in sliding contact with an inner peripheral surface of the reception groove. An oscillation center of the bearing race in the reception groove is positioned between the raceway rail-side rolling surface and the slider-side load rolling surface that are opposed to each other.</p> |
