The technical objective of the present invention is to provide an apparatus to maintain a closed state of a curtain, which can maintain a closed state of a curtain while minimizing usage of a hard magnet through optimum design, and can fixate the hard magnet and a rubber magnet without using a fixing member such as an insertion groove and an insertion protrusion. The apparatus to maintain a closed state of a curtain of the present invention is to maintain a closed state of a first blocking member and a second blocking member, and includes: a first and a second pocket part; a first and a second rubber magnet; a first and a second groove part; a first and a second upper ND magnet which are inserted into an upper part of the first and the second groove part respectively, have different polarities, and have neodymium (Nd) as a main component; a first and a second lower ND magnet which are inserted into a lower part of the first and the second groove part respectively, have different polarities, and have neodymium as a main component; a first friction member which surrounds the first upper ND magnet and the first lower ND magnet inserted into the upper part and the lower part of the first groove part respectively together with the first rubber magnet, and provides friction with an inner surface of the first pocket part; and a second friction member. |
