The first ply (32) has a first cord. The first cord is formed by twisting three yarns. The yarn is constituted by an aramid fiber. A fineness of the yarn is equal to or higher than 800 dtex and is equal to or lower than 1100 dtex. The second ply (34) has a second cord. The second cord is formed by twisting three yarns. The yarn is constituted by the aramid fiber. A fineness of the yarn is equal to or higher than 800 dtex and is equal to or lower than 1100 dtex.
