  FIG. 14 is a side view of the cleaning body provided in the fifth embodiment of the present invention, FIG. 15 is a view showing the behavior of dirt when the cleaning body provided in the fifth embodiment is used for cleaning, and FIG. It is a figure explaining the dimension of the cleaning object with which an embodiment is equipped.

  The fifth embodiment of the present invention includes a plate-shaped cleaning body 2 having a plate-like shape shown in FIG. According to the fifth embodiment configured as described above, as shown in FIG. 15, the bottom surface of the groove in step 14 is brought into contact with the protrusion 24 that forms the acute angle portion of the cleaning body 2 on the bottom surface of the groove in step 14. The effect of scraping and retaining the dirt 25 accumulated in the film is obtained, and the dirt 25 can be removed more efficiently.

  Further, since the volume of the cleaning body 2 entering the groove in the step 14 is smaller than that in the case where the disc-shaped cleaning body 2 is provided, the cleaning body 2 can increase the force of pressing and rubbing the bottom surface of the groove in the step 14. As a result, the cleaning efficiency can be improved.

  Here, the dimension of the cleaning body 2 provided with the projection 24 that forms a windmill-shaped acute angle portion is that the groove depth A of the step 14 is generally 10 to 11 mm as shown in FIG. In order to reduce the size and weight of the cleaning device main body and to maximize the area actually used for cleaning in the entire cleaning body 2, the diameter B is set to 86 to 102 mm, and the protrusion 24 forms an acute angle portion serving as a cleaning portion. Is preferably provided at four positions every 90 degrees.

  Further, as shown in FIG. 16b, if the height C of the protrusion 24 forming the acute angle portion is smaller than 11 mm, the volume of the cleaning body 2 entering the groove of the step 14 increases, and the groove of the step 14 is increased. The force of pressing and rubbing the bottom surface of the sheet will decrease. Further, since the volume for storing the dirt 26 that has been scraped off and accumulated becomes small, the amount of dirt reaches the storage limit relatively quickly, and the cleaning ability is reduced. On the other hand, as shown in FIG. 16c, if the height C of the protrusion 24 is too high, the volume of the cleaning body 2 is reduced, so that the rigidity of the cleaning body 2 is impaired, and the cleaning body 2 is distorted during cleaning. The problem that it ends up occurs. Therefore, the height C of the protrusion 24 is preferably about 11 to 15 mm which is slightly higher than the depth A of the step groove is generally 10 to 11 mm as shown in FIG.

  In each of the above-described embodiments, when cleaning the groove 15 in step 14, detergents that improve the cleaning accuracy are applied in advance to the upper surface of the cleaning body 2 or step 14, and the groove 15 of the cleaning body 14 is cleaned in this state. You may make it do.
