In addition, the zipper opening direction of the groove is notched. Further, a bulging portion facing the notch is formed in the pair of side leg pieces. In a state where the opening and closing device is attached to the flap portion of the bag, the concave portion and the convex portion of the zipper are restricted by the bulging portion and the notch, and the opening and closing device is prevented from coming off the flap portion. When the opening / closing member is slid in the direction in which the groove is formed (see FIG. 2 (E)), the uneven portion is pressed by the bulging portion formed in the side leg and enters the notch, and Mated. This will close the zipper. On the other hand, when the opening / closing member is slid in the opposite direction (the direction in which the notch is formed), the uneven portion is forcibly separated by the middle leg piece. That is, the zipper is opened.
