[Prior art]

 2. Description of the Related Art Conventionally, some gaze guide markers laid on the shoulder of a road to drive a vehicle safely use a reflective member that reflects light received by a headlight. However, dust and organic gas, and mud that bounced off the road surface during rainfall adhered to the surface of the reflective member, and the reflective performance was significantly reduced. As a result, in particular, the inner wall of the tunnel is contaminated and the lighting performance is significantly impaired, so that the reflecting member had to be cleaned regularly or as needed. Conventionally, in order to wipe off the dust adhering to the surface of the reflecting member, the surface of the reflecting member was cleaned by a manual wiping operation. However, this method required much time and cost. Other gaze guidance tools that attempt to solve this problem include, for example, those shown in FIGS. That is, the reflecting member b provided with the guide specimen a, the plurality of rotating blades d rotatably mounted on the surface of the reflecting member b using the mounting screw c, and the surface of the reflecting member b are wiped. A dust cleaning means f having a brush e mounted on a rotating blade d, a substantially L-shaped holding metal g provided with an induction specimen a, and a substantially box-shaped fixing member i having openings h at at least one end of the front and rear; A foot g of the holding fitting g in the opening h of the fixing member i. ₁ A support plate l provided with a gap j in which the foot portion g is detachably fitted, and the foot g attached to the support plate l₁And a spring member m provided so as to be capable of holding the holding fitting g by elastic contact with the holding member g. In order to attach the guide mark main body a to an attached body such as the interior material o of the tunnel T, for example, the notch i is provided in the opening h of the fixing member i.₁Through the screw head part p₁Using a set screw p capable of accommodating the fixing member i and the foot g₁The fixing member i is covered by inserting a screwdriver from above into the holes q, r, and s formed in conformity with the support plate l and the spring material m and rotating the set screw p. It was attached to the mounting body. Then, the rotating blades d are rotated using wind power, and when the rotating blades d rotate, the surface of the reflecting member b of the guide body a is wiped off with a brush e attached to the rotating blades d to perform cleaning. .

[0003]

[Problems to be solved by the invention]

However, in the above-mentioned conventional line-of-sight guide signs shown in FIGS. 4 to 6, the rotating blade d is simply mounted rotatably with respect to the reflecting member b using the mounting screw c. Thus, dust adhering to the surface of the reflecting member b, or I Flip insertion hole d ₁ provided on the rotary blade d as water rain or snow Tsu Furitsumo in winter has melted the mounting screws c is inserted, It penetrates into the back surface of the reflection member b. For this reason, since the rotating blade d cannot rotate smoothly with respect to the mounting screw c as the rotating shaft, the wiping performance of the reflecting member b by the brush e is impaired, and the reflection efficiency of the reflecting member b is reduced. The inconvenience was caused. The present invention solves the above-mentioned drawbacks, and prevents dust from entering from the female screw hole provided in the female screw cylindrical member so that the mounting screw as the rotating shaft is inserted, and moisture from rainwater or snow when snow melts. Accordingly, it is an object of the present invention to provide a gaze guidance device that prevents rotation of the rotating shaft smoothly, thereby maintaining good wiping performance of the brush against the reflecting member and preventing the reflection efficiency of the reflecting member from being reduced.
