Abstract:
A V-belt (B) includes a rubber composition forming a portion (11) to be V-shaped side faces (110). Organic nanofibers (16) and organic short fibers (17) are included in the rubber composition, and oriented along a belt width. In the rubber composition, a ratio of a storage modulus in a grain direction to a storage modulus in cross-grain direction is 5 or greater.
