PROBLEM TO BE SOLVED: To provide a coating gun for equally and sufficiently mixing two liquids, and for easily cleaning the inside of the gun after ejecting coating materials by a simple operation.SOLUTION: A coating gun includes: a gun body; an ejection head for atomizing and ejecting mixed liquid in which first liquid and second liquid is mixed; a handle part; an air guidance path communicated between the ejection head and the opening of the handle part for guiding compressed air to the ejection head; and a mixing chamber mounted on the neighborhood of the ejection head so as to be freely attachable/detachable for introducing the mixed liquid to the ejection head. The mixing chamber includes: a mixing chamber body 32 like a bottomed cylinder with an openable/closeable structure; a first liquid introduction pipe 56; a second liquid introduction pipe 58; and a mixed liquid introduction pipe 64. A meandering passage formed such that the first liquid and the second liquid flow in a meandering manner is disposed along the axial direction of the mixing chamber body 32 in the mixing chamber body 32. |
