The slider 20 is configured to be movable back and forth in the horizontal direction via a crank 24 that engages with a motor 22.

In the coating apparatus 2 configured as described above, the vehicle body 28 is conveyed inside the gate-shaped frame 4 at a predetermined speed via the conveying device 26. Then, when the vehicle body 28 reaches the coating work position of the coating apparatus 2, the side coating mechanisms 6a, 6b and the upper coating mechanism 8 are driven, and the coating guns 10a, 10b and 18a, 1 respectively.
Both sides of the vehicle body 28 and the roof that have been conveyed from 8b are painted. At that time, the sliders 12a and 12b are moved up and down through the cranks 16a and 16b under the driving action of the motors 14a and 14b, and the coating guns 10a and 10b are moved in accordance with the side shape of the vehicle body 28, and the respective coating is performed. The side painting work of the vehicle body 28 is performed by adjusting the amount of the paint injected from the guns 10a and 10b.
