In a linear guide bearing apparatus wherein a separator is interposed between adjacent balls K and K moving following a curved circulating path 8 , and the ball K contacts concave faces W of the separator T at both ends in an axial line direction and at the same time the ball K rolls as contacting a guide face 8 a of an outside guiding member 5 and a guide face 8 b of an inside guiding member 9 , the separator has an outer diameter larger than a maximum outer diameter Lphi under a condition where the ball rolls as simultaneously contacting both curved faces 8 a , 8 b of the inside and the outside of the curved circulating path 8 , and the radius of curvature of the guiding face 8 b in the curved circulating path 8 is reduced to a size not contacting the separator T.
