The design condition is that the orthogonality (horizontality) is maintained with high precision. However, in reality, it is difficult to maintain the parallelism between the suspension shaft and the ball screw and the horizontality of the bracket strictly. On the other hand, if the bracket is slightly tilted due to play with the hanging shaft that is rotatably inserted, the proper and smooth screwing rotation between the bracket and the ball screw cannot be obtained, and the initial purpose of shifting the rotating brush horizontally and parallel is not achieved. There is a problem that cannot be achieved properly.
