PROBLEM TO BE SOLVED: To heighten the safety without increasing weight by burying a cord which is bent at both ends and extended in zigzag substantially in the circumferential direction like a ribbon in coated rubber, making the winding start end and the winding end overlap each other, and specifying the overlap ratio to the width of a cord layer. SOLUTION: An endless belt B is one ribbon R formed by arranging one or plural cords<is in parallel and burying the same in coating rubber, which is bent at both ends off the belt and extended in zigzag substantially in the circumferential direction. The winding start end S and the winding end F are not bound and arranged in such a manner as to overlap each other, and the amount L of overlap is equal to or less than three times as large as the width of a ribbon-like rubber coating layer, preferably from two times to three times, both inclusive. Thus, the safety off the belt can be heightened<i without remarkable increase in weight of the tire.
