Claims

[Claims for Utility Model Registration] A swinging frame 38 that supports the cleaning head 39 on one side with the support shaft 41 as the center of rotation, and that the other side is attached to the holding parts 3 and 31 with the shaft 37 as the center of rotation. , the first one placed adjacent to this drawing frame,
Second and third link members 45, 47, 49
A first link member 45 of this link mechanism is connected to the cleaning head via a spring member 51 at one side thereof, and a first connecting shaft at an intermediate portion thereof. 46 as the center of rotation, connected to one side of the second link member 47,
The second link member 47 is attached to the swinging frame 38 at the other side so as to be rotatable about the support shaft 41, and the second link member 47 is attached to the third link member at the middle part.
One side of the link member 49 is connected to the second connecting shaft 48 as a rotation center, and the other side is connected to the other side of the third link member via a spring member 52, and the third link member is , the holding parts 3, 31 and the fulcrum shaft 50 are connected to each other at the other side end with the fulcrum shaft 50 as the center of rotation, and the direction and distance of the straight line L1 connecting the axes of the support shaft 41 and the first connecting shaft 46 are Cleaning characterized in that when uniform external pressure is applied to the cleaning head from the processing surface, the relationship is set to be parallel and equal to the direction and distance of the straight line L2 connecting the axes of the mounting shaft 37 and the fulcrum shaft 50.
