A cord of a toothed belt is made of a twisted yarn including a band-like material. The band-like material includes a filament bundle of high-strength glass fibers integrated together through a binder. The binder contains a rubber component, at least either a maleimide-based compound or a polyisocyanate compound, and a powdery inorganic filler. A surface of a reinforcing fabric facing opposite to the toothed belt body is coated with a surface-coating rubber layer made of a rubber composition containing a rubber component including hydrogenated nitrile-butadiene rubber as a main part.

A rubber-reinforcing cord (12) of the present invention includes at least one strand. The strand includes at least one filament bundle and a coating provided to cover at least a portion of a surface of the filament bundle. The coating includes a rubber component including at least one selected from the group consisting of carboxyl-modified nitrile rubber and carboxyl-modified hydrogenated nitrile rubber, an isocyanate compound, a bismaleimide compound, carbon black, and a rubber-modified epoxy resin. In the coating, the content of the isocyanate compound is 10 to 50 parts by mass, the content of the bismaleimide compound is 5 to 25 parts by mass, the content of the carbon black is 2 to 18 parts by mass, and the content of the rubber-modified epoxy resin is 5 to 30 parts by mass, with respect to 100 parts by mass of the rubber component.

A fiber-treating agent, where the fiber-treating agent is a one part fiber-treating agent including a single composition or a multiple-part fiber-treating agent including a plurality of compositions. The fiber-treating agent contains the following components (A) to (C) in a total composition thereof, and where, for the one-part fiber-treating agent, a part or all of the components (A) and (B) is optionally a condensate formed from the components: (A): a compound having a structure wherein a methylol group is bonded to each of two nitrogen atoms in the compound, (B): a phenolic compound having an electron donating group on at least one of meta-positions and a hydrogen atom on at least one of ortho-positions and a para-position, wherein the electron donating group on the meta-position optionally forms, together with adjacent carbon atoms, a benzene ring optionally substituted with a hydroxy group, and (C): water.

A rubber-reinforcing cord (30) according to the present invention includes: a reinforcing fiber or reinforcing fiber bundle (21); a first coating (22) provided to cover the reinforcing fiber or reinforcing fiber bundle (21); and a second coating (31) provided to cover the first coating (22) and be located at the outer surface of the rubber-reinforcing cord (30). The first coating (22) includes: first rubber including nitrile-based rubber as a main component; and a first crosslinking agent. The second coating (31) is a coating different from the first coating (22) and includes: second rubber consisting essentially of nitrile-based rubber; and a second crosslinking agent. The nitrile-based rubber is at least one selected from nitrile rubber, hydrogenated nitrile rubber, carboxylated nitrile rubber, and carboxylated hydrogenated nitrile rubber.
