<p>A belt durability is improved by effectively suppressing an interlayer separation between each widthwise outer end portion of a belt reinforcing layer 41 and a belt layer 34, in which each widthwise outer end 45 of one widest-width inner belt ply 35a is located outward from each widthwise outer end 46 of widest-width reinforcing plies 42a, 42b in 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 end 46 in the widthwise direction. Therefore, the each widthwise outer end portion of the inner belt ply 35a is easily reduced in the widthwise direction, whereby shearing deformation in section to the each widthwise outer end portion of the reinforcing ply 42a, 42b is reduced. <IMAGE></p> |
