Description of the Related Art There is a gap of about 60 cm in a connecting portion of a vehicle, and usually a passage hood is only installed at the center, and the side portion of the vehicle has a gap as it is. However, there is a risk that people and luggage on the home will fall on the track through this gap. Therefore, in recent years, Shinkansen vehicles and the like are equipped with fall prevention devices made of synthetic resin.

It is fastened to the end with a bolt 23. In the figure, reference numeral 24 is a U-shaped bracket attached to the vehicle side, and is attached by bolts 23 with attachment plates 25 and 26. In this example, the height h of the elongated body 21 is about 22 cm, the width w of the base 2 is about 10 cm, and a gap of about 6 cm is provided between the opposed tip portions 27, 27. Such a fall prevention device is intended not only to prevent a fall of a person or the like from the platform but also to reduce aerodynamic noise caused by collision between the vehicle and air during high speed traveling.

る。In this fall prevention device, a gap is formed in advance at the tip of the elongated body so that the opposing elongated bodies do not come into contact with each other at the place of the curve when traveling at high speed. Is not so much reduced. In the unlikely event that these materials come into contact with each other, if they come into contact with each other, many of them will be damaged immediately in the case of a hard material. It falls and cannot be used for a long time. Of course, there is a problem even if they do not come into contact with each other at the carve place, etc., and when driving at high speed, negative pressure is applied to the outside of the vehicle, which causes the elongated body to be pulled out to the outside. It has been found that the maximum force is applied and durability is not sufficient.

ある。The present invention is the fall prevention device as described above,
In order to withstand the negative pressure generated when the vehicle is traveling at high speed, the turn portion of the bellows is formed as a substantially V-shaped turn portion when vulcanizing and molding the rubber, and the fiber is mainly formed in the rubber film. The strength is increased by embedding a woven fabric or the like. Further, both end portions of the bellows are located on one side of the turn portion, and the attachment portion to the vehicle is a flat surface which is parallel to each other and serves as an attachment portion to the vehicle which is bent during vulcanization. . Therefore, the both ends are arranged so as to be directed toward the outer side of the vehicle and are attached, and the ease of attachment and the durability are improved.
