PROBLEM TO BE SOLVED: To provide a dancer roller device preventing bending in a belt-like body from occurring. SOLUTION: A dancer roller 2 and a curl preventing roller 3 are supported by a rod-like support member 4 and the support member 4 is swingably supported by a fulcrum O. When a tension of a belt-like fiber 7 increases, the dancer roller 2 is lifted by the tension of the belt-like fiber 7, the support member 4 swings around the fulcrum O, and the curl preventing roller 3 is pressed against a lower face of the belt-like fiber 7. Thus, curls are prevented from occurring.
