2. Description of the Related Art As this kind of sliding door device, for example, as described in Japanese Patent No. 3080349,
When the opening is closed, the two doors abut each other to form a continuous plane, and when one of the two doors is opened to open the opening, one of the two doors is opened. There is known a sliding door device in which the doors move in parallel to the outside of the other door so that the two doors overlap each other inside and outside.

[0003] This type of sliding door device comprises a first door which is guided by a first guide rail and traverses an inner moving path;
The first guide rail is supported by a laterally moving body that engages with a second guide rail parallel to the first guide rail via a parallel link mechanism, so that a path between the inside movement path and the outside movement path outside the inside movement path is provided. When configured to be capable of parallel movement, and the second door urged by the spring toward the inner movement path side, when both doors relatively approach from the closed state abutting each other in the inner movement path, A cam means for moving the second door into the outside moving path is provided.

[0004] However, the conventional sliding door device described in the above publication, when the first and second double doors are in the closed state in which they abut each other in the inner moving path, sets the butting ends of the two doors together. As the tip of the second door covers the tip of the first door,
The cross-sectional shapes are formed in mutually opposite wedge shapes, the wedge-shaped tip surface of the first door is a cam surface, and a cam driven roller is pivotally supported on the wedge-shaped tip portion of the second door adjacent to the cam surface. , From the cam surface and the cam driven roller, the cam means,
That is, the cam means for moving the second door into the outer moving path when the two doors relatively move closer from the closed state in which they abut each other in the inner moving path.

[0005]

In the above-mentioned conventional construction, the tip of the first door must be formed as a cam of the cam means. Along with the restriction, the tip of the first door itself becomes a cam surface, and the cam driven roller on the second door rolls, so the surface of the tip of the first door is worn. In order to prevent this, it is necessary to take measures such as protecting the area where the cam driven roller at the tip of the first door rolls with another member.
In addition, since a cam driven roller must be supported at the end of the second door so that a part thereof protrudes toward the first door, a special bearing unit is required for assembling the cam driven roller. And it was not easy to assemble the cam driven roller. Further, when the second door moves outside the first door, the cam driven roller is rolled on the surface of the first door to prevent sliding contact between the two doors. The surface of the door may be worn or scratched due to the rotation of the cam driven roller, and in order to prevent this, a flat rail surface on which the cam driven roller rolls is provided on the surface of the first door. It had to be provided, and the design of the surface of the first door was also restricted.
