The present invention relates to a bidirectional door closer which can respond to both opening and closing of a door as a single door closer. According to the present invention, first and second catching members and first and second unidirectional rotation dampers are operated in response to the opening and closing of the door by one rack gear member and one coil spring. The bidirectional door closer of the present invention comprises: a housing; a first catching member; a second catching member; a coil spring; a rack gear member; a first one-directional rotation damper; and a second one-directional rotation damper.
본 발명은 하나의 도어 클로저로서 도어의 열리고 닫힘 모두에 대응할 수 있는 양방향 도어 클로저로서, 하나의 랙기어 부재와 하나의 코일 스프링에 의하여 제1,2캐칭부재 및 제1,2일방향 회전 댐퍼가 도어의 열리고 닫힘에 작동하도록 한 것이다.
