PROBLEM TO BE SOLVED: To provide a coating gun capable of preventing the intrusion of liquid supplied to a storage chamber of a rotary atomizing head into the back side of the inner part of a body. SOLUTION: A discharge path 37 which is communicated with an annular clearance 27, is opened outside the body 10 and is nearly radial is disposed on the back side from the annular clearance 27 between the outer periphery of a passage pipe 12 and the inner periphery of a center hole 26 of the rotary atomizing head 11. The liquid passes through the annular clearance 27 from the storage chamber 17 of the rotary atomizing head 11, advances to the discharge path 37 thereon, is imparted with a centrifugal force through the rotation of the rotary atomizing head 11 and is discharged outside the body 10 by the centrifugal force. As a result, there is no fear that the liquid is intruded into the interior of the back side in the inner part of the body 10. COPYRIGHT: (C)2005,JPO&NCIPI
