It will be opened. Where Sunawa Chi first door pairs are opened more than a predetermined angle, the door in the second door pair begins to open.

[0015] Thus, the door in the first door pair and a second door pairs adjacent to this, it is somewhat opened, these doors laterally along the guide rail via the running body You will be able to slide. Therefore when sliding the respective door in the lateral direction, with the force the second door pair-out line is opened is folded Ri folding <br/>, further third by a second door pairs of door When the door at the door pairs are opened together subsequent third, fourth, Ru are opened in sequence folded also the doors pair of the 5 ‥‥‥.

When the first door pair is slid in the closing direction from the open position, the door pairs other than the terminal door pair slide along the guide rail in a folded state , and the force travels. It is closed because a closing force is applied to the inner door of the door pair of the terminal through the body . When the door is further closed by a predetermined angle or more, the closing force of the door is applied to the outer end of the power arm via the link, so that the power arm is rotated counterclockwise. And to the door of the adjacent door pair
Since the closing force is applied via the power arm and the transmission delay mechanism , the door is closed. Multiple door pairs, that by the sliding force will be sequentially closed in, and finally the closing by the first door pair are closed completed.
