PROBLEM TO BE SOLVED: To provide a small-sized automatic zip-fastener which can be automatically operated or closed, used in clothes and tents. SOLUTION: The zip-fastener is composed of a small-sized motor 30 and a worm wheel 34 rotated by the motor 30. A guide tube 24 and an automatic slider 21 are moved along the edge of the zip-fastener by the rotation of the motor 30, because the worm wheel 34 ties both sides of the teeth 4 of the zip- fastener. This move meshes or releases the teeth 4.
