2. Description of the Related Art Conventionally, a connecting passage is provided in a portion where rail cars, for example, trains and passenger cars are connected to each other, so that passengers can come and go between adjacent cars. The corridor is covered with a bellows-shaped hood, and the metal cross plates attached to each vehicle overlap each other to form the floor, on which passengers can walk. .

The structure of such a transition plate will be described with reference to FIGS. 4 to 6. One of the transition plates 3 is attached to the bracket 2 fixed to one of the vehicles 1 via the support shaft 4, and the vehicle 1 It is fixed so that it does not tilt downward with respect to. On the other hand, a bracket 6 is fixedly mounted on the other vehicle 5 connected to the one vehicle 1 by a connector (not shown), and the other crossing plate 7 swings on the bracket 6 via the support shaft 8. It is movably supported. The tip 7a of the other transition plate 7 is placed on the upper surface 3a of the one transition plate 3 and is supported in the vertical direction. As a result, the pair of crossing plates 3 and 7 overlap with each other to absorb the relative displacement between the vehicles 1 and 5, while forming a floor surface on which passengers can walk.

[0004]

By the way, since the above-mentioned conventional crossing plates 3 and 7 are in direct contact with each other, as shown in FIG. 5, they are rubbed against each other due to the relative displacement between the vehicles 1 and 5. As a result, as shown in FIG. 6, abrasion, scratches, and rusting A occur on the upper surface 3a of the one connecting plate 3 due to contact with the tip 7a of the other connecting plate 7, and the back surface of the other connecting plate 7 7b is contacted with the tip 3b of one of the transition plates 3 to cause abrasion, scratches and rust B, which is not preferable in appearance.

Further, in extreme cases, as the two vehicles 1, 5 swing in the vertical direction, the two crossing plates 3, 7 hit each other to generate a loud metallic noise, which is not preferable in terms of noise prevention.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to not only reliably prevent wear, scratches, rust, and tapping noises, etc., which occur on the transition board, but also the transition board and the vehicle body of a railway vehicle. It is an object of the present invention to provide a bridge plate protection device for a railway vehicle that can be easily installed without modification.
