Abstract
Toothed belt comprises teeth and bottoms which are alternately formed at one surface of the toothed rubber layer of the toothed belt. A fabric is provided at the outer surface of the teeth and the bottoms. A back rubber layer is integrally provided at the other surface of the toothed rubber layer. A plurality of cords are interposed at the interface between the toothed rubber layer and the back rubber layer. A large number of modified microfibers are intermixed throughout the toothed rubber layer. The modified microfibers consist of a copolymer of polyolefin and nylon fiber. The modified microfibers are oriented in the length direction of the toothed belt as a whole.
