Provided is a rolling guide device which is capable of preventing uneven wear of a holding belt by alleviating a tensile force that acts on the holding belt when the holding belt circulates in an endless circulation path together with rolling elements. The endless circulation path has a guide groove configured to guide movement of the holding belt in the endless circulation path. A condition of tmax<δ is satisfied, where: tmax represents a maximum clearance between both end portions of the holding belt which are opposed to each other in the endless circulation path; δ is expressed by δ = 2 ∫ 0 π 2 ( a sin θ ) 2 + ( c cos θ ) 2 d θ - 2 ∫ 0 π 2 ( c sin θ ) 2 + ( b cos θ ) 2 d θ ; 2c represents an interval between the holding belt in a load path and the holding belt in a return path; A represents a depth to an arc top point of an outer peripheral surface of the guide groove in a direction change path; B represents a depth to an arc top point of an inner peripheral surface of the guide groove in the direction change path; “d” represents a thickness of the holding belt; and a=(A−d/2) and b=(B+d/2) are satisfied.
