Abstract:
Provided is a toothed belt that has satisfactory durability even under high-temperature and high-load conditions or within an oil or water environment. The toothed belt 10 comprises a belt body 13 including a tooth rubber portion 11 and a backing rubber portion 12. A surface of the tooth rubber portion 11 is covered with a facing fabric 20. The facing fabric 20 is subjected to RFL treatment, and has an outer surface 21 covered with a hardened material of a first epoxy resin. The softening point of the hardened material of the first epoxy resin is, for example, 110° C. or higher. The epoxy equivalent of the first epoxy resin is, for example, 100 to 1500 g/eq. Alternatively, the facing fabric 20 is subjected to impregnation treatment with a treatment agent including a second epoxy resin, a hardener for hardening the second epoxy resin, and a rubber component.
