Abstract
A power transmission belt includes a belt body made of rubber and a cord embedded in the belt body. The belt body has a portion having the cord embedded therein, and the portion is made of a rubber composition having a storage normal modulus at 25° C. in a grain direction of 80 MPa or more and the ratio of the storage normal modulus at 25° C. in the grain direction to a storage normal modulus at 25° C. in a cross-grain direction of 1.20 or more to 2.50 or less. The rubber composition is arranged such that the grain direction corresponds to a belt length direction and the cross-grain direction corresponds to a belt width direction.
