As described above, according to the present invention,
When attaching the fall prevention member, the fall prevention member can be attached simply by inserting a small screw from the rear part of the mounting frame and pulling the connecting member, so the installation work is easier than the conventional installation with many screws. In addition, since both ends of the fall prevention member are sandwiched by a wide area, the mounting portion becomes solid. Furthermore, since the screw for mounting the fall prevention member is not exposed on the found surface, the appearance is refreshed and the appearance can be improved.

[0037] Further, the more to prevent the disengaged missing attachment end of the fall prevention member by the engagement projections can be in the mounting more firmly. According to the second aspect of the present invention, the fall prevention member is sandwiched between the attachment members so that the fall prevention member has an inner wall portion inclined toward the connecting passage and an outer wall portion parallel to the vehicle outer plate. Can be naturally formed and held in a divergent shape. Therefore, when the opposite fall prevention members are pressed against each other, the fall prevention members bulge and deform toward the connecting passage, and the vehicle is placed on the platform where the rail is bent so that the radius center of the curve is on the platform side. When the vehicle stops or passes, the fall prevention member does not protrude to the platform side and hinders passengers on the platform, which is safe. Further, since it does not protrude from the vehicle outer plate surface, it does not exceed the vehicle width limit.

Further, since the fall prevention member spreads toward the end, in other words, the mounting side is formed in the bottom recess, the lateral width (mounting space) of the mounting member may be short, so that a rain gutter or the like is attached to the vehicle body. The fall prevention member can be easily attached to a narrow space.
