The coupling groove part 200 is formed on the front surface of the base part 100, protrudes from the base part 100, and is formed in a slot shape with an open top. Specifically, the coupling groove 200 may be composed of a slot 210, an upper opening 220, and a central opening 230.

The slot 210 secures the engaging projection 300 to the base 100, determines the position of the engaging projection 300, and prevents it from being detached from the front surface of the base 100.

The upper opening 220 is formed in an open state on the upper part of the slot 210, and the coupling protrusion 300 is inserted into the slot 210 through the upper opening 220.

The central opening 230 is formed in an open state on the front surface of the slot 210 and is connected to the upper opening 220, and the connecting portion 500 connected to the coupling protrusion 300 is connected to the central opening 230.

The coupling protrusion 300 is detachably coupled to the coupling groove 200. The engaging projection 300 is formed in a shape corresponding to the engaging groove 200 and is inserted and removed from the engaging groove 200.

Thus, by inserting the coupling protrusion 300 into the coupling groove portion 200, the coupling protrusion 300 can be fixed to the base portion 100, that is, the installation surface, so the attachment and detachment of the coupling groove portion 200 is easy.

Accordingly, the second connection part 520 connected to the reflection part 400 may rotate freely with respect to the first connection part 510.

Specifically, the reflector 400 may rotate around the first direction perpendicular to the ground to adjust the inclination angle (left and right reflection angle) of the reflector 400 relative to the installation surface. This makes it easy to recognize the light reflected by the reflector to the driver driving away from the installation surface. For example, light may be reflected to a driver driving a curved lane, or light may be reflected to a driver driving a lane outside of a wide road.

The reflector 400 may be rotated around a second direction perpendicular to the installation surface to adjust an inclination angle (up and down reflection angle) of the reflector 400 with respect to the ground. According to the installation environment of the road guidance display device, the reflector 400 installed on a ramp or the like may be installed at an optimal angle.

The reflector 400 may be rotated around a third direction parallel to the ground and the installation surface to adjust the height of the reflector 400.

A connection protrusion 521 having a shape corresponding to the connection groove 511 is formed on a coupling surface with.

The connecting groove 511 has a narrower cross-section than the bottom of the inlet, and the connecting protrusion 521 is formed with a wider cross-section toward the end. Thereby, the connecting projection 521 is fitted to the connecting groove 511.

The connecting groove 511 and the connecting protrusion 521 are formed in a circular cross section, so that the first and second connecting portions 510 and 520 can be rotated relative to each other.

Thus, the second connection unit 520 connected to the reflection unit 400 rotates around a direction perpendicular to the installation surface to adjust the up and down reflection angle of the reflection unit 400.
