Beschreibung
Zusammenfassung:	The present invention relates to a V-ribbed belt in which a friction transmission surface of a compression rubber layer is coated with a knit fabric. The compression rubber layer is formed of the cured product of a rubber composition containing an ethylene-α-olefin elastomer and carbon black wherein the carbon black contains a soft carbon having a primary particle diameter of at least 40 nm and a hard carbon having a primary particle diameter of less than 40 nm. The ratio between the number of particles of the soft carbon and hard carbon is former/latter = 3/97 to 25/75.
