By manually pushing the handle 2b of the door body 2 in the opening direction Y indicated by the solid line in the opening direction Y, the door body 2 connects the shaft 8a of the connecting shaft portion 8 and the rotary support 3 to the upper support arm 4 and the lower support arm. Although it rotates in the clockwise direction Z by 5, the movement in the front-rear direction is restricted by the guide portion 6 and the guide rail 7, so it moves along the guide rail 7 toward the left rotation support column 3 and moves at one point. After the door is open halfway as indicated by the chain line, it is reached when the door is fully open as indicated by the two-dot chain line. On the other hand, with respect to the door main body 2 at the time when the door is fully opened, which is indicated by the chain double-dashed line, by applying manual force to the handle 2b in the closing direction X, the door 2 moves in the direction opposite to the movement path from the time when the door is fully closed to the time when the door is fully opened. As described above, in the automatic swing door 1, the combination of the connecting shaft portion 8 and the cam portion 9 causes a slight human power to be applied, and even if the hand is released, the door is automatically opened with a half-open line indicated by a one-dot chain line and then the solid line. Return when the door is fully closed. Also, if the hand is released from the door body 2 when the door is half-opened, which is indicated by the alternate long and short dash line, while moving in the opening direction Y, the process automatically returns when the door is fully closed, which is indicated by the solid line. The movement locus described in detail here takes the same movement locus in normal times even in an automatic swing door provided with the door emergency opening tool 11 of the present invention described later.
