<p>A V-belt (23) is wound around a driving pulley (21) so as to be sandwiched between first and second sheaves (21A,21B) and wound around a driven pulley (22) so as to be sandwiched between first and second sheaves (22A,22B). The V-belt (23) includes: an intermediate rubber layer (43) in which a plurality of cores (46) are embedded; an upper rubber layer (44) provided above the intermediate rubber layer (43); and a lower rubber layer (42) provided below the intermediate rubber layer (43). A length of a portion of the core (46) thorough a first left lateral surface (51L) and a length of a portion of the core (46) exposed through a first right lateral surface (51 R) are each equal to or less than a half of a length of the core (46).</p> |
