Abstract:
1. A transmission belt that includes a rubber layer that has ethylene-α-olefin elastomer used as a base rubber and extends in a belt longitudinal direction, and core wires adhered to the rubber layer and embedded therein in the belt longitudinal direction, wherein the rubber layer adhered to the core wires is formed to have a storage modulus of not less than 10 MPa and not more than 50 MPa and a tan δ of not more than 0.15 as measured by dynamic viscoelasticity measurement under conditions at a static load of 3 kgf/cm 2 , a dynamic strain of 0.4%, a frequency of 10 Hz and a temperature of 25° C. in a tensile mode in a belt longitudinal direction, wherein ethylene-propylene-diene-terpolymer, which contains dicyclopentadiene as a diene component, is used for the ethylene-α-olefin elastomer.
