PROBLEM TO BE SOLVED: To provide a rolling guide device which alleviates a tensile force acting on a holding belt when the holding belt circulates in an endless circulation path together with rolling bodies, and can prevent the eccentric wear of the holding belt.SOLUTION: A guide groove for guiding the movement of a holding belt is formed in an endless circulation path, and a maximum clearance between both ends of the holding belt opposing each other in the endless circulation path is set as t, a clearance between the holding belt in a load passage and the holding belt in a return passage is set as 2c, a depth up to a disc circular apex of an external peripheral face of the guide groove in a direction conversion path is set as A, a depth up to a disc circular apex of an internal peripheral face of the guide groove in the direction conversion path is set as B, and a thickness of the holding belt is set as d, a=(A-d/2), b=(B+d/2). A relationship of t<δ is satisfied with respect to δ which is expressed in a formula.SELECTED DRAWING: Figure 4 【課題】保持ベルトが転動体と共に無限循環路内を循環する際に、保持ベルトに対して作用する引っ張り力を軽減し、保持ベルトの偏摩耗を防止することが可能な転がり案内装置を提供する。【解決手段】無限循環路内には保持ベルトの移動を案内する案内溝が形成され、無限循環路内で互いに向かい合う保持ベルトの両端部の最大すき間をｔmax、負荷通路内の保持ベルトと戻し通路内の保持ベルトとの間隔を２ｃ、方向転換路における前記案内溝の外周面の円弧頂点までの深さをＡ、前記方向転換路における前記案内溝の内周面の円弧頂点までの深さをＢ、前記保持ベルトの厚みをｄ、ａ＝（Ａ−ｄ／２）、ｂ＝（Ｂ＋ｄ／２）とし、と表現されるδに対して、ｔmax＜δを満たすようにした。【選択図】図４
