, The other door 2 opens and closes. At this time, the traveling body 30
Since the rack 5 is mounted on the vehicle, the rack 5 moves smoothly due to the smooth running of the running body 30 by the running rollers 31, and the door 2 opens and closes smoothly. In addition, the guide roller 7 rolls along the hanging piece 29, the upper frame 3 runs stably, and the door 2 is stably opened and closed. In addition, since the roller 27 of the lifting prevention member 8 is in rolling contact with the positioning plate 19, the upper frame 3 is prevented from rising upward when traveling, and the door 2 is prevented from rattling up and down, so that the door 2 can be opened and closed with good stability. can do. When the door 2 is closed, the brake unit 40 rides on the stopper 41, and the door 2 stops,
It is possible to prevent the mating portion of the door 2 from colliding strongly.

[0015]

As described above, according to the present invention, the door wheel provided on the upper frame of the upper end of the door is mounted on the upper rail so as to be freely movable, and the pair of doors can be opened and closed right and left. A pair of long running bodies are arranged in the upper rail body, and the running body is made to run freely by running rollers provided on the running body. A pair of racks are interlocked with a pinion interposed therebetween, and the upper frame of one door of the pair of doors is connected to one traveling body and the upper frame of the other door is connected to the other traveling body. The rack and the pinion allow the pair of doors to be linked, and the pair of doors can be linked and opened and closed, as well as the rack and the pinion, so that the structure can be made simpler than before, and Etc. will be reduced. Even if it breaks down, maintenance is easy, and the rack is mounted on a running body that can run in the longitudinal direction of the upper rail with running rollers, so the rack runs smoothly on the running body and the door opens and closes Can be done smoothly.

In the invention according to the second aspect of the present invention, a traveling body is provided so as to be able to travel freely above and below the rear chamber of the upper rail body, and travels between the front room and the rear chamber of the upper rail body. Since the holding member that keeps the body from coming off is detachably attached, the running body can be easily removed from the upper rail body by removing the holding member, and the running body, rack, and pinion can be easily removed by removing the running body. Etc. can be easily maintained.

Further, in the invention according to claim 3 of the present invention, a brake portion is integrally protruded from the longitudinal end of the traveling body, and a stopper on which the brake portion rides when the pair of doors is closed is raised. Because it is provided on the rail body, even if the rack runs smoothly on the traveling body and the door opens and closes smoothly, when the door is closed, the brake part rides on the stopper and the door stops. In addition, it is possible to prevent a collision in which the mating parts of the door are strongly hit when the door is closed.
