業を迅速かつ容易に行える。According to the present invention, the paint booth body-side portions of the paint feed pipe and the paint return pipe are housed in the air supply chamber, and the paint feed pipe and the paint return pipe-side portions of the paint booth body. A structure in which the coating means in the coating chamber is connected via a feed branch pipe and a return branch pipe, a part of the feed branch pipe is drawn out of the coating booth main body, and a filter is detachably mounted on the drawn part. As a result, the temperature of the paint circulated and supplied to the paint chamber can be kept constant while reducing the size and cost of the paint booth, and the filter replacement operation can be performed quickly and easily.
