No. 451316. The pole has the form of an elongated cylinder or an elongated cone with a small taper, and is made by extrusion molding, blow molding or injection molding of a general-purpose polyurethane resin-based thermoplastic elastomer or polyethylene resin mixed with a pigment of the required color tone. It is provided with air holes that allow the air inside the pole to escape when stepped on the vehicle. In each of the sign posts, a reflective sign band made of a retroreflective tape is provided on the pole so that a driver or a pedestrian riding in a vehicle traveling at night can easily recognize the sign.

[0004]

Such road signposts are installed on roads for centerline signs on roadways, lane guidance displays, traffic regulation guidance displays for channelization, and the like. However, the road sign pillars that have been installed have been replaced because the reflective sign strips have peeled off. The replacement is done by cleanly peeling off the old reflective sign strip, wiping off the dirt on the pole, and attaching a new reflective sheet to the pole. At this time, since the pole is considerably contaminated with exhaust gas, mud, dust, etc., it is necessary to wipe off the pole with a detergent or the like. The dirt is fairly heavy, and it is adsorbed on the pole.To adhere the new retroreflective tape to the pole, it is necessary to thoroughly clean the pole surface. Peel again at home.
However, the replacement work must be performed within a very limited time in order to minimize the traffic regulation time, and the poles cannot be completely cleaned, so that peeling occurs again in a short period of time.

An object of the present invention is to provide a reflection sign device for a road sign pole, which can restore the reflection performance easily and in a short time, and can maintain the restored reflection performance for a long period of time. It is.
