In order to improve the operability, the inventor of the present invention has proposed a pair of narrow side doors supported on one track of a guide which is arranged above and below the opening and closing opening and closing, respectively, and has two rows of tracks arranged side by side. A wide center door disposed at the center of both side doors when closing the opening and closing supported by the other track, wherein the side door moves twice as much as the center door movement amount 1 The development of a double speed mechanism for a sliding door that can be moved in conjunction with the amount is advanced and completed, and is filed in Japanese Patent Application No. 8-29935.
No. 2 was filed.

In this double speed mechanism, an endless belt is stretched around a pair of pulleys rotatably supported at both ends in the width direction of a center door, and the endless belts are positioned at desired upper and lower positions which are maximally separated from each other. The ends of the stays protruding from the opposite side ends of the two side doors toward the center door are connected. When one side door is moved by a certain distance, the other side door is also linked by the same distance via the endless belt. When the center door is moved in one direction by a certain distance, the pulley itself moves together with the center door, and the side door on the other side can move with twice the moving distance of the center door. ing. With this development, the amount of movement of the person who opens and closes the slide door is small, and the slide door can be opened and closed with an extremely simple operation.
