Abstract
A belt durability is improved by effectively suppressing an interlayer separation between each widthwise outer end portion of a belt reinforcing layerand a belt layer, in which each widthwise outer endof one widest-width inner belt plyis located outward from each widthwise outer endof widest-width reinforcing pliesin the widthwise direction and hence reinforcing elements of the belt plies are not crossed with each other at the outside from the each widthwise outer endin the widthwise direction. Therefore, the each widthwise outer end portion of the inner belt plyis easily reduced in the widthwise direction, whereby shearing deformation in section to the each widthwise outer end portion of the reinforcing plyis reduced.
