PROBLEM TO BE SOLVED: To allow an operation of cleaning the inside of a discharge tube necessary for the prevention of clogging to be properly and quickly performed in a sealer gun in which suction actuation of a pump device assembled to a body achieves elimination and removal by the suction into an expansion/contraction chamber of the pump device via the inside of the discharge tube.SOLUTION: A pump device P includes: a cylindrical casing 60 fitted into an inner cavity of a distal end part of a body (a); a piston 61 fitted into the casing 60; a suction block 62 assembled to a front end side of the casing 60; and a suction/discharge pipe 64 which is connected to a suction/discharge opening 63 provided at the suction block 62 and of which the base end side is held in the suction block 62. The suction block 62 of the pump device P is detachably assembled to a front end part of the casing 60, and is fixed to the casing 60 by the assembly by a locking part C for the body (a) distal end part of the discharge tube 2.
