PROBLEM TO BE SOLVED: To integrate a dental floss with its related device, to provide an economical device storable together in any type of dental floss case for convenience of storage and carrying, to have the strength superior to the function of a conventional device, and to simplify its usage. SOLUTION: This device is required to have a simple, short, and thin shape. The dental floss is provided with a knotted stop beforehand. The device is dispensed with any extra structure including a long grip except for providing a stop receiver to be engaged with the stop. A flat plate without any curve is molded by forming a U-shaped notch alone for stretching the dental floss so as to secure the thinness. These means can solve the problem, the simplification and the miniaturization can improve the operability, and the simplification of the usage and the long-time repeated use can produce the economy.
