<P>PROBLEM TO BE SOLVED: To provide a linear guide device capable of preventing contact between rollers and suppressing generation of skew of rollers using a simple shaped spacer rollers without using components such as a retainer having a complicated shape or a roller chain, and capable of preventing reduction in rigidity and in dynamic rated load. Ž<P>SOLUTION: In the linear guide device 1, a plurality of cylindrical rollers 4 as rolling elements roll and circulate in an endless circulation passage 40. When r denotes a radius of a spacer roller 5 and R denotes a radius of a roller 4, the cylindrical spacer roller 5, having a radius which satisfies the relationship of r>R<SP>2</SP>/4R, is inserted between adjacent rollers 4.
