The present invention consists of a fixed body embedded in the ground and thinly exposed on the road, and a divided structure of a post installed upright through the fixed body to restrict the passage of vehicles, so that replacement and repair are easy in case of damage due to a vehicle collision, In addition, the fixed body is a common installation type structure that can selectively install the gaze guide rod and the lane divider, and furthermore, the fixed body is provided with reflectors in all directions, which also serves as a road signer. A part that can contribute to road traffic safety due to various functions It relates to an interchangeable multi-functional traffic guide facility, which is arranged in a concentric circle with a holding post (100) disposed upright on a specific road and restricting passage, and a perforated area formed on the road, and the upper part is a form in which the holding member is detachable The fixed body 200, which is connected with an upright installation induced, and the restraint body 300, which is disposed to enter the perforation area of the road through the upper part of the fixed body, is intervened through the restraint body, and is added by the intervention. It is composed of a bolt body 400 that allows the constraint body to be constrained in position on the corresponding road while the constraint body is expanded as much as the volume and the perforation area and close pressure are exerted.
