If the tilt in the front-rear direction of the rotation center shaft 13 does not become a non-tilt state even if the lower links 74, 74 ′ are swung in the vertical direction, the main body 62 of the front-rear direction tilt adjustment unit 61 is rotated. When the main body 62 rotates, the offset arm 10 swings up and down around the swing fulcrum P1 of the offset arm 10 to adjust the tilt of the rotation center shaft 13 in the front-rear direction to a non-tilt state. To do. Whether or not the rotation center shaft 13 is in a non-inclined state in the front-rear direction is determined by the above-described level.
[00 30 ]
Accordingly, the vertical positional relationship of the rotary shafts 23, 32, and 44 of the heaven field processing unit 21, the preprocessing unit 31, and the trimming unit 41 constituting the working unit 20 can be made constant, The working unit 20 can be rotated while keeping the positional relationship constant. As a result, when the position of the working unit 20 with respect to the offset arm 10 is changed, it is possible to prevent a situation in which the performance of the fringing work by the working unit 20 changes.

The rotation center shaft 13 can be brought into a vertical state by adjusting the tilt of the rotation center shaft 13 in the front-rear direction side of the rotation center shaft 13 to the non-tilt state by the main body 62. Accordingly, the working unit 20 can be rotated in the horizontal direction while keeping the vertical positional relationship between these parts constant, and when the position of the working unit 20 with respect to the offset arm 10 is changed, It is possible to reliably prevent a situation in which work performance changes. In addition, once the vertical adjustment of the rotation center shaft 13 is performed once by the coater-side connecting device 50, the subsequent vertical adjustment work is unnecessary, so that the work efficiency of the entire work of the paintbrushing work can be improved.
[00 33 ]
