PROBLEM TO BE SOLVED: To provide an inexpensive rolling guide device in which a raceway base and a moving base are incorporated via a plurality of rolling elements, and a mounted object fixed to the moving base can be freely reciprocated along the raceway base.SOLUTION: The rolling guide device 10 has the raceway base 11 formed as a long member, and the moving base 21 incorporated to the raceway base 11 via the plurality of rolling elements 31. The raceway base 11 is formed in a u-shape in the cross section having a recess 12 with one surface side opened by performing sheet metal press work of a metal plate member, and is formed with a rolling element rolling surface 13 on which the rolling elements 31 roll along a longitudinal direction with respect to an inner surface of the recess 12, and the moving base 21 is formed with an endless circulating surface 25 on which the rolling elements 31 circulate endlessly. The endless circulating surface 25 includes a load rolling element rolling surface 25a on which the rolling elements 31 roll while applying loads thereon, a pair of rolling element direction changing surfaces 25b, 25b provided to both ends of the load rolling element rolling surface 25a, respectively, and a no-load rolling element rolling surface 25c for transferring the rolling element 31 in a no-load state from one side of the rolling element direction changing surface 25b to the other side thereof.
