[Means for Solving the Problems]

 In order to achieve the above object, the cleaning brush according to the invention of claim 1 is a cleaning brush in which bristles are planted on a flocking table to form a flocked portion, in the vicinity of the central part on the flocking table. With the bristles in the center row as the center, bristles with longer hair length were planted as they approached the bristles in the row near the center. In addition to the structure of claim 1, the cleaning brush according to the invention of claim 2 forms bristles having a higher hardness than the bristles of the other rows in the bristles of the row near the central portion to form the bristles. It has been configured. In addition to the structure of claim 1, the cleaning brush according to the invention of claim 3 has a bristle having a hardness higher than that of the row of bristles near the central portion on the flocking table and is planted in the bristles of another row. The table is formed.

[0006]

[Action]

 According to the structure of claim 1, since the bristle length of the cleaning brush becomes longer as it approaches the row near the center of the flocking table, the brush surface contacting the object to be cleaned has an inclined surface. It becomes convex. This convex surface makes it easier to contact the corners, corners, recesses, etc. of the object to be cleaned, and it is possible to scrape off the stains on the corners, corners, recesses, etc. of the object to be cleaned that are difficult to remove with a normal brush. According to the configuration of claim 2, the hardness of the bristles in the rows near the central portion on the flocking table is higher than the hardness of the bristles in the other rows. As a result, the cleaning brush increases the rigidity of the bristles in the rows near the center, which are frequently used, and can maintain the cleaning function for cleaning the corners, corners, and recesses of the object to be cleaned for a long period of time. . According to the structure of claim 3, the hardness of the bristles in the other rows is higher than the hardness of the bristles in the row near the central portion on the flocking table. As a result, the tufts in the rows near the center are protected by being pinched around the tufts in the other rows that have obtained a stronger rigidity by increasing the hardness of the bristle. That is, the bristles near the central portion do not bend extremely, are not damaged, and the cleaning brush can be used for a long period of time.
