  The second embodiment for carrying out the present invention shown in FIG. 10 to FIG. 12 is mainly different from the first embodiment for carrying out the present invention in the form of a plate having one end portion formed on an inclined surface 28. The joint member 6A is provided with a rainwater discharge portion 15A that is not connected to the joint plate 13A and the rain gutter 27 but has a rainwater discharge port 26 on the side surface on the other case 4 side, and does not form a draining portion on the bottom surface. Even in such a transition passage joint device 1A, the same effects as those of the first embodiment for carrying out the present invention can be obtained.

In addition, by providing the rainwater discharge port 26 on the wall surface side of the other housing 4, water is discharged along the wall surface of the other housing 4, or rainwater flows on the guide rail 12 and is discharged from both ends of the guide rail. Therefore, it is possible to prevent rainwater from falling into the lower passage of the crossing passage 5A.
The third embodiment for carrying out the present invention shown in FIGS. 13 and 14 is mainly different from the first embodiment for carrying out the present invention in that one crossing passage 5 is provided in one housing 3. The joint 2 between the passage 5 and the other housing 4 is closed by one joint member 6, so that the joint device 1 B for the passage is used to implement the present invention. The same effect as that of the first embodiment can be obtained.

  In this way, when the passage 5 does not have the passage 5 on the lower floor, for example, when the passage just below the passage is a road, the ground, etc., the joint device 1B for the passage is used to walk directly under the passage. It is possible to prevent people from falling on the rain.

  In the embodiment of the present invention, the one end side of the joint member is supported by a roller or a suspension roller. However, these rollers are used for smooth sliding movement of the joint member in the left-right direction. Therefore, joint members may be installed without using them.

Moreover, although the form which fixed the rainwater discharge part to the bottom face of the bottom cover was demonstrated, you may use bottom cover itself as a rainwater discharge part.
Furthermore, although not provided in the embodiment of the present invention, a support roller may be provided on the upper part of the pair of handrails to support the handrail cover member. By comprising in this way, the slide movement to the left-right direction of a handrail cover member can be made smooth.

  The present invention is used in the industry of manufacturing joint devices for crossing passages.
