PROBLEM TO BE SOLVED: To provide an exterior body having a large curvature radius on a crown part of a skirt formed on an outer surface of a sheet, during shrinking of an elastic extension member, and a production method therefor.SOLUTION: Both side parts of elastic extension members in a width direction, are respectively fixed to fixing parts disposed in a width direction of two sheets with a predetermined interval, then, the two sheets are fixed on a coupling part extending in the width direction and formed on an intermediate part in a vertical direction of the elastic extension members adjacent in the vertical direction, and the width of the coupling part in the vertical direction is set to become 10-15% with respect to an interval of the elastic extension members adjacent in the vertical direction.SELECTED DRAWING: Figure 7 |
