PURPOSE: To reliably prevent slip between a mouthpiece tool and a resin-made liner when a resin layer made of FRP is subjected filament-winding mold on the outer surface of the resin-made liner, by providing projecting parts on one part on the outer side surface of the mouthpiece tool to be brought in contact with the resin-made liner and locking it on the resin-made liner. CONSTITUTION: A fiber reinforced resin-made tank Te is provided with a tank main body 1 formed by laminating a resin layer 3 made of fiber reinforced resin on the outer surface of a resin-made liner 2, a flange part 7 to be locked on the inner surface side of the opening edge of an attaching hole 4, and an exposing part 8 exposing outside the tank main body 1 are provided on the attaching hole 4 provided on the tank main body 1, and a metallic mouthpiece tool 5 on which an internal thread part 9 is formed is attached. In this mouthpiece tool 5, the upper part of a perforating part 6 to be inserted through the attaching hole 4 is formed on a taper surface 10 opening outward from the tank, a plurality of linear projecting parts 12b are formed on the outer surface of the mouthpiece 5, and the projecting parts 12b are reliably locked on the opening edge of the attaching hole 4. |
