The rail plate is installed on the prop to maintain the standard height at all times. When a general passenger car collides with the guide rail, the large bone is opened and the other bone is opened to absorb the shock, and the shock absorbing member also absorbs the shock and bounces off by reflection. The guide rail can reduce the damage caused by collisions or collisions with other vehicles traveling with the third impact by the above phenomenon. The structure was designed.

In addition, after cutting the corrugated portion in the form of a luminous plate on the guide rail plate of the present invention (in this case, one side is not cut out), the cut-out portion is perpendicular to the guide rail plate, and the luminous sticker is attached to the upright portion. By attaching the luminous plate and the guide rail plate formed in one body,

Conventionally, the luminous plate is attached to the guide rail plate by welding or bolt nut to prevent the luminous plate falling off the guide rail plate or the luminous plate falling off the guide rail plate due to the collision of the vehicle, thus preventing the driver from driving at night. It was.

When installing, it is installed 90mm higher than the standard guide rail plate, and the posts are also 100mm long, and the posts are made of two holes at 100mm intervals to adjust the height to 200mm.
