<p>PURPOSE: To make possible to use a normal centeral closing member having a singly rotatable closing element, and make the closing member to be a flat structure by passing a retracting string through the upper part of the closing member arranged underneath, and guiding the string through the upper part arranged on the member. CONSTITUTION: A retracting string 6 is passed through the guiding member of a both guiding portion 12 from the both ends of a centeral closing member 4, and reached at the upper by further passing through the guide member 5 of a tongue portion 2. The string 6 is extended from the upper to the lower, and come out from the guiding portion 13 located on the member 4, and passed through the first guiding member 14 of the guiding portion 10. The string 6 is further passed through the guiding portion 15 of a closing holding member 3, thereafter, further passed through the guiding member 16 of the guiding portion 10, and finally passed through the guiding member 17 of the tongue portion 2. Like this, in order to close the upper portion 1 of the member 4, the retracting string 6 is reached at a belt member 7 of the lower side while drawing two upper loops on the upper of the member 4. Thus the upper is closed by the retraction of the two upper loops on the upper of the member 4.</p> |
