PROBLEM TO BE SOLVED: To provide a curtain belt which can form uniform wave patterns having the same length of the wave pattern over a perpendicular range of a hanging curtain without an additional assistance, and can keep the same condition. SOLUTION: In the condition that a carrier belt 4 gathers no pleats in a longitudinal direction 7 and spreads out in the longitudinal direction 7 maximally, a space 12 between adjacent two guide grooves 6 is at least the same size as a minimum range 8 of the guide groove 6, and preferrably, at least a double size. Furthermore, the minimum range 8 of the guide groove 6 is at least 1 cm, and preferrably, at least 2 cm. COPYRIGHT: (C)2009,JPO&INPIT
