Abstract

First, a first belt ply is wound around an outer peripheral surface of a belt drum having a curvature so as to be formed as a tubular shape, and a rubber layer protruding to an outer side than an end portion in a width direction of a belt reinforcing layer is arranged in an outer periphery of an end portion in a width direction of the first belt ply. Further, a second belt ply which is narrower than the first belt ply is wound around an outer periphery of the second belt ply so as to be formed as a tubular shape, and a belt layer is formed in such a manner that the first belt ply and the second belt ply are laminated. The belt reinforcing layer is formed by spirally winding a rubber-coated reinforcing cord around an outer peripheral side of the formed belt layer, and an end portion in a width direction of the belt reinforcing layer is arranged in an outer side than the first belt ply.
