Abstract
A power transmission belt has a cord embedded in a belt body made of rubber. The cord is configured as a plied yarn with a total fiber fineness of 4000 to 5000 dtex. The plied yarn consists of four primarily-twisted yarns, each being obtained by subjecting a bundle of para-aramid fibers with a fiber fineness of 1000 to 1250 dtex to a primary twist in one direction at a twist coefficient of 1200 to 1350, and these four primarily-twisted yarns are then secondarily twisted in the opposite direction to the primary twist at a twist coefficient of 900 to 1100, thereby obtaining the plied yarn.
