The state is longer, and the door 3 is opened by opening and closing the door 3 only when the car enters and exits. Therefore, the appearance of the door 3 is particularly problematic in terms of time. However, the appearance in the extended state becomes a problem. Then, in the present invention, at the time of spreading as shown in FIG. 1 in which the appearance is problematic, the shaft 7 positioned at the opening 10a of the bearing 10 in a state where the adjacent gate panel element bodies 1 are spread. Since the outer surface is set so as to face the inner surface of the groove 5, the outer surface of the shaft 7 is not visible from the outside, and only the outer surface of the bearing 10 is visible to the outside. Therefore, the phenomenon in which the outer surface of the shaft portion 7 that has been scratched by sliding contact with the inner surface of the bearing portion 10 appears to shine outside is eliminated. At this time, although the groove 5 is provided so that the outer surface of the shaft 7 located at the opening 10 a of the bearing 10 is not visible from the outside, there is a gap between the inner surface of the groove 5 and the outer surface of the bearing 10. Since the bearing 11 is formed, the outer surface of the bearing 10 seen from the outside does not slidably contact with the inner surface of the groove 5 and is not damaged.
By seeing only the outer surface of the camera, a beautiful state can be visually recognized forever.

By the way, as in the present invention, the shaft 7 is connected to one end of the substantially semicircular concave groove 5 formed on the side surface of the side frame 4 via the neck 6 so as to form the substantially semicircular concave groove 5. The protruding piece 9 protrudes toward the center side of the arc, and protrudes from the center of the back surface of the vertical frame member 8.
Is provided to form the hinge body 2, and the shaft portion 7 is rotatably fitted into both bearing portions 10 of the hinge body 2.
As shown in FIG. 4, the width of the gap between the outer surface of the shaft portion 7 located at the opening 10a of the bearing portion 10 and the back surface of the vertical frame member 8 is increased, and there is a possibility that a finger may be packed in this portion. Groove 5
A finger piece 2 for preventing finger stuffing along an extension of the arc of the substantially semicircular concave groove 5 from the base protruding the neck 6 at one end of the wall.
4, the shaft 7 is positioned just at the opening 10a of the bearing 10 in the folded state as shown in FIG.
The gap between the outer surface of the vertical frame member 8 and the back surface of the vertical frame member 8 is hidden by the protruding piece 29, so that the finger is prevented from being packed in this portion. Further, as described above, since the time when the telescopic gate 3 used for the entrance of the garage or the like is folded is shorter than that in the extended state, the appearance is not so much a problem as in the extended state. 4, the opening 10a of the bearing 10 when the protruding piece 29 is folded.
In this case, the outer surface of the shaft portion 7 damaged by the sliding contact is not seen from the outside, and the appearance is improved.

The structure of the pivotal connection between the upper and lower connecting bars 14, 15 and the hinge 2 'is not particularly limited, but may be the same as that of the gate panel 1 and the hinge 2 described above. Is also good.
