PURPOSE: A zipper jamming prevention structure including a stitch unit and a patch unit is provided to prevent fabric from jamming to a zipper, and to produce the stitch unit and the patch unit using various shapes and colors. CONSTITUTION: A zipper jamming prevention structure includes an outer layer(10), an element(20), a slider(30), a first wing unit(40), and a stitch unit(50). The outer layer forms the outside of a tent, a bag, or clothes, and is produced with a high-durability material including polyester or nylon. The element is formed on the outside of the outer layer in a teeth-set form, for offering the movement route to a zipper. The slider moves along to the row of the element for rapidly opening and closing an open space. The first wing unit is produced with the same material with the outer layer. The stitch unit is formed on the first wing unit.
