본 발명은 내외로 개방되는 양쪽개방 도어에 설치될 수 있는 에어 댐퍼에 의해 완충되는 자동도어 폐쇄 힌지와, 상기 자동도어 폐쇄 힌지를 구비한 양쪽개방 도어 구조에 관한 것으로서; 자동도어 폐쇄 힌지(1)는 실린더(2)내의 조작 로드의 외주면의 대향하는 위치에 대략 V 형으로 형성되어 외주상으로 연속하는 캠 홈(35)에, 대향하는 위치에 볼(43)을 계합하고, 압축코일 스프링(5)의 복원력으로 하방으로 가압되는 압축 링(4)에 볼(43)를 계합하고, 볼(43)의 캠 홈(35)에 대한 이동과 압축 링(4)을 상하 움직임이 연동되도록 형성함과 동시에, 캠 홈(35)의 하측에 형성되는 캠 홈(35)과 대략 같은 형태의 캠 홈(36)에, 대향하는 위치에 볼(65)을 계합하고, 피스톤(6)에 볼(65)을 계합하고, 볼(65)의 캠 홈(36)에 대한 이동과 피스톤(6)의 상하 움직임이 연동되도록 구성되며, 피스톤(6)의 하강에 대응하여 실린더(2)내의 피스톤(6) 하측의 에어를 서서히 유출한다. An automatic door closing hinge configured to absorb a shock by an air damper which can be installed on a double swing door opening inward and outward and a double swing door structure provided with the automatic door closing hinge are provided. An automatic door closing hinge 1 is configured in such a manner that balls 43 are engaged with a cam groove 35 formed on an outer peripheral surface of an operating rod in a cylinder 2 at opposed positions so as to have a substantially V-shape continuing in a circular shape at opposed positions thereof, the balls 43 are engaged with a compression ring 4 urged downward by a restraining force of a compression coil spring 5, the movement of the balls 43 with respect to the cam groove 35 is in conjunction with the vertical movement of the compression ring 4, balls 65 are engaged with a cam groove 36 being formed under the cam groove 35 and having substantially the same shape as the cam groove 35 at opposed positions thereof, the balls 65 are engaged with the piston 6, the movement of the balls 65 with respect to the cam groove 36 is in conjunction with the vertical movement of the piston 6, and air on the lower side of the piston 6 in the cylinder 2 is gradually flowed out according to the downward movement of the piston 6.
