Beschreibung
Zusammenfassung:	The present invention pertains to a toothed belt that is made of rubber and comprises: a belt body including a plurality of tooth sections formed of a first rubber composition and provided at a predetermined interval in a longitudinal direction, a back section formed of a second rubber composition and integrated with the tooth sections, and core wires embedded in the back section in the longitudinal direction; and a tooth cloth covering the surfaces of the plurality of tooth sections, wherein the first rubber composition forming the tooth sections contains a composite polymer containing a hydrogenated nitrile rubber and a metal salt of an unsaturated carboxylic acid at a mass ratio (former/latter) of 100/80-100/180, and with respect to 100 parts by mass of the composite polymer, the first rubber composition contains 3-50 parts by mass of zinc oxide, 3-50 parts by mass of a non-reinforcing filler, 10 parts by mass or less of a reinforcing filler, 5 parts by mass or less of short fibers, and 1-5 parts by mass of an organic peroxide.
