Zusammenfassung:	A linear motion guide device having a long-life slider is provided. The linear motion guide device includes a guide rail, a plurality of rolling elements, and a slider. The material of the slider body 11 is alloy steel containing 0.1 mass% or more and less than 0.3 mass% of C, 0.5 mass% or more and 1.5 mass% or less of Cr, and 0.1 mass% or more and 0.4 mass% or less of Si, with the balance being Fe and inevitable impurities. An amount of retained austenite in a surface layer 14F of a slider-side rolling groove 14 subjected to a carburizing heat treatment is 15 vol% or more and 45 vol% or less. The surface hardness of the slider-side rolling groove 14 is Hv 650 or more.
