The reflection portion 13 and the reflection portion 53 are provided by attaching a reflection sheet from the outside of the metallic color coating film.

The metal color coating contains metal powder in the coating film, and specifically contains metal powder composed of about 20 to 30 parts by weight of aluminum powder with respect to 100 parts by weight of the solid component of the paint. .
By the inclusion of the aluminum powder, the pole 11 on which the metal-colored coating film is formed and the beam portion 5 are provided so as to be visually recognized in a metallic appearance. However, the configuration is not limited to this, and other configurations may be used in which the appearance of the coating film is metallic. For example, metal powder other than aluminum powder may be mixed, or a method other than mixing metal powder may be used.

The road marking body 10 was visually observed by installing the road marking body 10 by providing the pole 11 and the beam portion 5 so as to be visually recognized in a metallic appearance by the coating film of the metal color coating. If the driver of the vehicle misidentifies the road marking body 10 as being made of metal and does not damage the vehicle by touching the road marking body 10, it is possible to expect a positive effect of avoiding the road marking body 10. Contamination and damage can be suppressed.
The coating film of the metallic color coating is made to visually recognize a metallic appearance by forming the metallic powder into a transparent coating. By adding 20 parts by weight or more of the metal powder to 100 parts by weight of the solid component of the transparent paint, the surface to be coated with the metal color coating film is well concealed by the metal powder. It is preferable because it can be provided so as to be visually recognized as a metallic tone. Further, if the content of the metal powder is too large, the flexibility of the coating film is lowered. Therefore, in order to form the coating film so as to be able to follow the elastic deformation of the pole 11 and the beam portion 5, It is preferable that the metal powder contained in addition to 100 parts by weight of the component is 80 parts by weight or less.

The joint 4 is formed such that the surface roughness of the outer surface thereof is larger than the surface roughness of the outer surface of the pole 11 on which the metal color coating is applied, and the surface roughness of the outer surface of the beam 5 on which the metal color coating is applied. It is formed larger than this.
The surface roughness here is the arithmetic average height Ra of the contour curve measured by a method according to JIS B 0601 (2011), and the contour curve on the surface of the pole 11, the beam 5, and the joint 4. When the arithmetic average height Ra is measured by the same measurement method according to the JIS, the Ra of the joint 4 is formed to be the largest.

By making the surface roughness of the outer surface of the pole 11 and the beam 5 different from the surface roughness of the outer surface of the joint 4, the pole 11, the beam 5, and the joint 4 are separated from the viewer who has viewed the road marking body 10. It can be intuitively recognized that it is a member.
Then, the joint 4 having a large surface roughness is attached to the pole 11 and the beam 5 coated with metal color, so that the metal pole 11 and the beam 5 are connected to the joint 4 formed by casting. It can be misunderstood as if the vehicle has been installed, and an effect of positively urging the driver of the vehicle who visually observes the installed road marking body 10 can be expected.

The joint 4 has a metal color coating on the entire outer surface thereof. Specifically, the joint 4 has a metal color coating of the same metal color as the pole 11 and the beam portion 5.
By applying the metallic color coating to the joint 4, the joint 4 has a more appearance like a cast metal product, so that the road marking body 10 is easily misidentified as being made of metal.
Further, even when the joint 4 is painted or not coated with a metal color, the outer surface of the joint 4 having a surface roughness larger than that of the pole 11 and the beam portion 5 is formed by metal casting. The effect of making the viewer misidentify that the joint 4 is painted in such a color tone can be expected.

Further, as shown in FIGS. 1 and 3, the road marking body 10 is formed so that the outer diameter of the joint 4 is larger than the outer diameter of the beam portion 5 at the connection portion between the joint 4 and the beam portion 5. Yes.
By forming the joint 4 in this way, the beam part 5 formed separately is attached to the joint 4 intuitively as compared with the case where both outer diameters are formed to the same size. It can be provided in the visually recognized appearance. A joint in which the difference in outer diameter at the connecting portion between the joint 4 and the beam portion 5 is combined with the surface roughness of the joint 4 formed larger than the beam portion 5 to form the metal beam 5 by casting. 4 can be provided with an appearance that makes it easier to misidentify.

In the road marking body 10, the outer diameter of the joint 4 and the outer diameter of the pole 11 are formed to be approximately the same in the connection portion between the joint 4 and the pole 11. However, the present invention is not limited to this. . That is, the outer diameter of the joint 4 may be formed larger than the outer diameter of the pole 11 as in the connection portion between the joint 4 and the beam portion 5.
By providing in this way, the difference in the outer diameter at the connection portion between the joint 4 and the pole 11 is combined with the surface roughness of the joint 4 formed larger than the pole 11 to form the metal pole 11 by casting. It is possible to provide an appearance that makes it easier to misidentify as if it is connected to the joint 4.
Thus, at least one of the connection portion between the joint 4 and the pole 11 or the connection portion between the joint 4 and the beam portion 5 is formed to have a larger outer diameter than the connected member. It is preferable that the outer diameter of the joint 4 is larger than the outer diameter of the connected member.

  The road marking body 10 according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, the pole 11 of the column part 1 is provided with the reflection part 13 by a reflection sheet. However, the reflection part 13 may be formed of a reflector other than the reflection sheet. 13 may not be provided.
Further, the beam portion 5 is provided with the reflection portion 53 by the reflection sheet. However, the reflection portion 53 is not limited to this, and the reflection portion 53 may be formed of a reflector other than the reflection sheet. It is not necessary.
