A first supplementary fabric117and a rainwater guiding fabric118are equipped between an inner door fabric112and a first zipper tape113attached to this, and a first waterproof tape114is attached on the sewing line of the reverse of the first supplementary fabric117, so the rainwater that comes into the first zipper tape113by thee rainwater guiding fabric118can be guided downward to be discharged. And, by attaching a second waterproof tape104to the part of the sewing line that is formed when sewing a second supplementary fabric109to which an outer door fabric102and the second zipper tape103attached to this are connected, rainwater can be prevented from penetrating through the sewing line of the outer door fabrics102.
