PROBLEM TO BE SOLVED: To provide a metal roller connecting band superior in flexibility and suitable for circulation in a circuit. SOLUTION: Balls 14 are circulated in a load rolling passage B, a non-load return passage A and a pair of direction change passages C connecting the load rolling passage B to the non-load return passage A. The roller connecting band 26 for rotatably holding the series of balls 14 is formed of a metal in a wavy shape all over the length in the longitudinal direction. Ridge portions 31 and valley portions 32 of the wavy shape extend in the cross direction perpendicular to the longitudinal direction of the roller connecting band 26. COPYRIGHT: (C)2004,JPO&NCIPI
