PROBLEM TO BE SOLVED: To stabilizer the flow of a coating material and improve the quality of coating by making a joint having a flow channel without steps for connecting a coating material hose in the case a coating material is supplied to a spray gun for coating. SOLUTION: The joint serves as a connection port at the time of supplying a coating material to a spray gun main body and the installation side to the spray gun is composed of a sheet body and sheet presser which is enabled to freely rotate in the outer circumference of the sheet body and screwed in the spray gun and fixed by the sheet presser. Having sheet parts which are to be air-tightly brought into contact with each other and have no steps with a coating material inlet path formed in the main body side, the sheet body is connected. The sheet parts are brought into contact with each other through tapered faces, and the installation positions can be fixed at a free angle to the path axis. COPYRIGHT: (C)2009,JPO&INPIT
