The invention provides a rubber composition for a driving belt. On the basis of every 100 parts of rubber by mass, the rubber composition for the driving belt is prepared from the following componentsin parts by mass: 100 parts of rubber, 1 to 10 parts of fatty amide lubricant, and 2 to 7 parts of hydroxy stearic acid ether or hydroxy stearic acid salt. The rubber composition for the driving belthas the advantage that the surface friction coefficient is lower. The manufactured driving belt has the advantages that the viscous sliding noise is effectively reduced in the running process, the lasting low friction coefficient is ensured, and the like.
