This chatter bar is a product that has low impact and noise, and has little danger when it comes off the road surface.
This chatter bar made of urethane rubber is formed by integrally forming a retroreflective lens (cat's eye) 200 on a main body 100 in which a pigment such as yellow is added to a high-strength urethane rubber material, and is visually recognized as compared with a conventional aluminum chatter bar. (The aluminum chatter bar is metallic and has poor visibility), and the noise at the time of getting on the wheels of an automobile is low. Therefore, it should be installed on the stop line of the pedestrian crossing and the parking lot entrance stop line in addition to general use. Is increasing.

In recent years, light-emitting post cones and car stops have been installed in consideration of the visibility of pedestrians and bicycles at night as a way to make people friendly.
As a road fence corresponding to this requirement, a guide fence having a luminescent resin layer 130 on the main body 100 as shown in FIGS. 13 and 14 is disclosed. (Patent Document 2)
However, since the main body 100 is made of a metal material and the light emitting unit 130 has a phosphorescent material kneaded in a resin having high hardness at the center of the main body 100, there are problems of impact, noise, and visibility.
Moreover, since the light emission part (light storage part) 130 is a structure in which the center part of the main body 100 is fitted, there is a problem that it is difficult to see at night.
