る。In the automatic door closing apparatus constructed as described above, when the door 1 is opened as shown in FIGS. 1 and 2A, the link 6 swings according to the degree of opening of the door, and the link 6 Since one end is attached to the door-side automatic closing mechanism 8, the other end of the link is moved by swinging of the link. This causes the sliding body attached to the link tip to move along the guide. This movement of the sliding member causes the tension spring 77 of the closed door buffer mechanism 7 to be pulled in accordance with the amount of movement of the sliding member, and the tension increases. Accordingly, the force of the torsion spring 81 of the automatic closing mechanism 8 in the direction in which the door closes is weakened, and the door is slowed down and securely closed.
