The strong stretchable region has stretch stress in the width direction which is stronger than that of the weak stretchable region. On a position adjacent to a width inside part of the side seal on the weak stretchable region, there is provided a weakest stretchable region where the stretch stress is smallest in the weak stretchable region.
