Abstract: A respiration aiding device capable of giving a little sense of incompatibility and causing no interference with respiration with no concern about coming off after a long-term use. The respiration aiding device comprises a link portion having both ends to be inserted into the right and left nares, and a pair of right and left nasal septum presser portions attached to the ends of the link portion. A dimension of the right and left nasal septum presser portions is smaller than the diameter of the nares. Magnets are mounted at opposite positions in the nasal septum presser portions so that a north pole of one magnet and a south pole of the other magnet is disposed in confronting relation to each other.
