PROBLEM TO BE SOLVED: To improve adhesion between the rubber layers of a belt and adhesion between a rubber part and a cord while heat resistance of a multiprotrusion belt is improved and to provide durability even during the use of a belt in high temperature atmosphere. SOLUTION: A hydorogenerated nitrile rubber composition is respectively used in rubber applied on the canvass of the canvass layer 3 of a multiprotrusion belt 1, rubber formed at a compression rubber layer 4, and rubber formed at an adhesion rubber layer 5. A first skin of RFL formed by using nitrile rubber or hydrogenerated nitrile rubber as latex and a second skin formed of a hydrogenerated nitrile rubber composition and covering the first skin are formed on the surface of a cord 9 embedded in the adhesion rubber layer 5. |
