The side wall 51 is formed in a curved surface so as to become narrower toward the front and rear of the column 5, and is formed so that the front and rear of the column 5 are opened narrower than the connecting wall 52. A concave groove 53 is formed at the end of each side wall 51 at the front and rear of the column 5 so that the opening is directed to the end.

  The size of the concave groove 53 and the interval between the concave grooves 53 are formed so as to correspond to the size and interval of the ridges 14 formed on the side surfaces 17 on both sides of the unit body 1 of the self-luminous unit. The unit body 1 is fixed to the column 5 by inserting the protrusion 14 into the groove 53 on the front side with the front surface 16 facing the outside of the column 5. Since the unit main body 1 is fixed by inserting the ridges 14 into the concave grooves 53, the unit main body 1 is firmly fixed on the side surfaces 17 on both sides, and the direction and the like do not easily shift. In this embodiment, since the length of the concave groove 53 is formed so that the unit main bodies 1 can be stacked and installed in a plurality of stages, each unit main body 1 is simply inserted into the concave groove 53. It can be easily stacked. Further, since the LEDs 2 of the unit main body 1 are arranged in a line in accordance with the direction of the ridge 14, when a plurality of unit main bodies 1 are stacked in the same concave groove 53, the LED 2 of each self-luminous unit is automatically Are arranged as rows along the same direction.

  In addition, since the upper surface 18 and the lower surface 19 of the protective cover portion 12 of the self light emitting unit are each formed in a flat surface, when a plurality of self light emitting units are inserted into the same concave groove 53 and stacked, There is no gap between itself and the main body 1. Thus, by forming the upper surface 18 and the lower surface 19 of the protective cover portion 12 corresponding to the end portion of the unit main body 1 in the direction in which the ridge portion 14 is formed so as to correspond to the respective shapes, a plurality of When the self-luminous units are stacked in the same concave groove 53, no gaps are formed between the unit main bodies 1 so that they can be mounted with good fit. In the present embodiment, the upper surface 18 and the lower surface 19 of the protective cover portion 12 are formed in a simple plane. However, by providing unevenness and inclination corresponding to each of them, the vertical direction of the unit body 1 is mistaken. It is possible to prevent mistakes such as mounting.

  Since the concave groove 53 on the rear side of the support column 5 is formed with the same size and interval as the concave groove 53 on the front surface side, the unit main body 1 of the self-luminous unit can be inserted. Instead of 1, a reflector 9 having retroreflectivity is inserted into the concave groove 53 and fixed. In this way, the self-luminous unit is formed into a unit shape in which the protrusion 14 is inserted and fixed in the concave groove 53, so that other members having protrusions having the same size and interval as the protrusion 14 are combined. A product such as the self-luminous line-of-sight guidance mark S can be configured. As an example, in the present embodiment, only the unit main body 1 of the self-luminous unit is stacked on the front side of the support column 5, but a part of the unit body 1 may be replaced with the reflection plate 9 or formed on the support column 5.

Further, since the unit main body 1 can be stacked by engaging with the concave groove 53 corresponding to the ridge portion 14 as in the present embodiment, the length of the concave groove corresponding to the ridge portion 14 is changed. Thus, the number of unit bodies 1 to be stacked can be easily changed. For example, the number of unit bodies 1 attached to the self-luminous visual guidance indicator S can be changed by adjusting the length of the concave groove 53, and the length of the self-luminous visual guidance indicator S itself can be changed and the number corresponding to the number can be changed. It is also possible to attach the unit main body 1.

  Further, four LEDs 2 housed in the unit main body 1 are arranged in a line at equal intervals. At this time, as shown in FIG. 5, the distance between the LED 2 arranged at the upper end of the row and the upper surface of the unit body 1 and the interval between the LED 2 arranged at the lower end of the row and the lower surface of the unit body 1 are adjacent LEDs 2. It is arrange | positioned so that it may become a size of 1/2 of the space | interval L between. By arrange | positioning in this way, when the some unit main body 1 is arranged in parallel, the space | interval of adjacent LED2 can be arrange | positioned as the space | interval L equally. By arranging in this way, the light intensity of the LEDs 2 arranged in a row may partially change when the LEDs 2 of the stacked unit bodies 1 are turned on or blinking in synchronization. And uniform light can be emitted.

  Further, the reflector 4 provided in the unit body 1 is provided so as to extend from the upper surface 18 to the lower surface 19 of the unit body 1 so as to form two lines sandwiching both sides of the LED 2 row. When a plurality of unit main bodies 1 are stacked on 5, the reflector 4 is also arranged so as to be visually recognized so as to form two rows of lines. For this reason, when the unit main bodies 1 are stacked and arranged like the self-luminous line-of-sight guidance mark S, the light that is irradiated from the front and retroreflected is visually recognized as a vertically long line. Similar to the light emission of the LED 2, a road linear perception effect using perspective can be obtained.
