Summary:To strike a balance between prevention of scattering of coating liquid to be splayed and quality of a coating film by readily moving a coating applicator to any working position using a pneumatic propulsion device.SOLUTION: A self-propulsion type coating applicator (10) includes: a pneumatic propulsion device (11); a spray nozzle (12) for forming a spray port (121) on an outer side of an operation region of the pneumatic propulsion device (11); supply means (13) for supplying coating liquid to the spray nozzle with a pressure of 1 MPa or less; and a contact frame (14) extending farther than the spray port (121) and coming into contact with a work plane (W) to be splayed with the coating liquid by the spray nozzle (12).SELECTED DRAWING: Figure 1 【課題】空気推力装置を用いることによって塗装機を任意の作業位置に容易に移動させ、かつ吹き付けられる塗液の飛散防止と塗膜の品質とを両立させる。【解決手段】自己推進式塗装機（１０）は、空気推力装置（１１）と、空気推力装置（１１）の動作領域の外側に吹付口（１２１）を形成する吹付ノズル（１２）と、１ＭＰａ以下の圧力で吹付ノズルに塗液を供給する供給手段（１３）と、吹付口（１２１）よりも先まで延びて吹付ノズル（１２）が塗液を吹き付ける作業面（Ｗ）に接触する接触フレーム（１４）とを備える。【選択図】図１
