摘要： A toothed belt is provided with toothed portions arranged at a regular pitch in a belt length direction. A belt body is made of a rubber composition containing, as a main ingredient of a rubber component, ethylene-α-olefin elastomer having an ethylene content of 44% by mass to 66% by mass. A reinforcing fabric is adhered to a surface of the belt body on a toothed side, with a reinforcing fabric adhesion coat interposed between the reinforcing fabric and the belt body. The reinforcing fabric adhesion coat is made of a rubber composition containing hydrogenated nitrile-butadiene rubber as a main ingredient of a rubber component.

摘要： A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and provided to be embedded in the belt body and to form a helical pattern having a pitch in the belt width direction. When the cord is viewed from a side orthogonal to its length direction, an angle 0 of an outermost filament in the filament bundle of the carbon fibers forming the cord with respect to the length direction of the cord is 8° or more to 20° or less.

摘要： In a toothed belt including a toothed belt body and a reinforcing cloth, the toothed belt body includes a rubber composition and has a base part formed into a flat band shape and a plurality of rubber tooth parts, which are arranged integrally with one face of the base part and spaced apart from each other in a belt lengthwise direction. The reinforcing cloth is attached to the toothed belt body to cover a face, of the toothed belt body, with the rubber tooth parts. Each of the rubber tooth parts is covered with the reinforcing cloth in a corresponding one of cloth-covered tooth parts where a rate of a volume of the reinforcing cloth with respect to a volume of the cloth-covered tooth part is 60% or more.
