Description

  The present invention relates to a light leakage prevention device for preventing outdoor light from entering a room from the side edge of the curtain when the window is covered with the curtain.

  Conventionally, a first fastening body is attached to a mating edge of a one-side hanging curtain that is opened and closed, and a second fastening body that forms a mating member of the first fastening body is paired with the hanging curtain to open and close. There is disclosed a curtain aligning tool attached to a mating edge of the other side hanging curtain (see, for example, Patent Document 1). In this curtain aligning tool, the first and second fastening bodies have magnetized surfaces that can be attracted to each other by the attracting action of the magnets held on at least one side thereof. In addition, the first and second fastening bodies have a function as a weight that maintains the hanging posture of the edge of the hanging curtain on which they are mounted.

  In the curtain aligner configured in this way, when the curtain is closed, the curtains are naturally combined so as not to leave the alignment edges of the left and right curtains, so that the curtains can be prevented from being blown or fluttered by the wind. It is like that.
