PROBLEM TO BE SOLVED: To provide a rolling element receiving belt which can reduce circulation resistance caused by the rubbing of the tip end of the rolling element receiving belt with the inside wall or the guide groove of an endless circulation path without reducing the load capacity and the rigidity of a linear motion guide, and further to provide the linear motion guide. SOLUTION: The linear guide 10 (a linear motion guide) has a guide groove 60 formed inside the endless circulation path 28 so as to extend along it. The rolling element receiving belts 50 guided by the guide groove 60 to circulate are built in the respective endless circulation paths 28. The rolling element receiving belts 50 are formed so as to have both terminals, and have a plurality of rolling element receiving portions for individually receiving balls 46. Connecting arm portions 52 for defining the rolling element receiving portions located at both terminal portions among the rolling element receiving portions are formed so as to have thin walled portions 56 thinner than other connecting arm portions 52.
