PROBLEM TO BE SOLVED: To provide a rolling body housing belt capable of reducing frictional resistance in circulating along a turnaround passage and further to provide a linear motion guiding device equipped with the rolling body housing belt. SOLUTION: The rolling body housing belt 50 is used for the linear motion guiding device with an endless circulating passage where a plurality of balls 46 runs in a rolling manner. The rolling body housing belt 50 comprise a plurality of spacers 51 interposed between adjacent balls 46 inside the endless circulating passage and a flexible belt-like joining arm 52 which joins the spacers 51 mutually. The joining arm 52 contributes to uniform geometric moment of inertia in an inner and outer circumferential directions of the endless circulating passage over its entire length as a result of making a portion located in the middle between each of adjacent spacers 51 thicker as compared with the other portions with respect to the thickness in the inner and outer circumferential directions of the endless circulating passage.
