PROBLEM TO BE SOLVED: To prevent precipitation of the coating effectively and reduce piping costs while ensuring high original coating distribution functions. SOLUTION: A coating going conduit 4 and a coating coming conduit 5 are disposed so as for them to extend along two arrangement rows for coating gun mounting portions 2. In each of the coating gun mounting portion 2, a coating outlet portion 11 for taking out a coating T to be fed to the coating gun 3 is formed by arranging a by-pass conduit 12 connecting the coating going conduit 4 to the coating coming conduit 5 in a shortcut manner, branching a coating outlet conduit 13 from the by-pass conduit 12 and arranging an outlet valve 15 opening/closing the coating outlet conduit 13. The coating going conduit 4 is constant in the diameter over the whole length, while the coating coming conduit 5 increases gradually in the diameter toward its downstream.
