PROBLEM TO BE SOLVED: To provide a linear rolling guide apparatus which hardly causes a spin friction between balls and a Gothic arc groove formed on a guide rail and a slider. SOLUTION: The Gothic arc groove 10 to be used as a ball rolling groove formed on the guide rail and the slider of the linear rolling guide apparatus is formed by two circular arcs 11, 12. The ratio of the maximum contact pressure of the balls 5 to be brought into contact with one circular arc 11 to the maximum contact pressure of the balls 5 to be brought into contact with the other circular arc 12 is set to be 0.3 or more or 0.
