Abstract
An endless metallic belt has at its outer peripheral surface a layer provided with a compressive residual stress by shot peening, and also has at its inner peripheral surface a layer provided with a compressive residual stress by shot peening. In a method for manufacturing the endless metallic belt, both outer and inner peripheral surfaces of the endless metallic belt are subjected to shot peening, wherein the inner peripheral surface is shot peened prior to the outer peripheral surface. The method produces an endless metallic belt having its fatigue strength improved without suffering any significant deformation.
