a joint formed to penetrate through from one of opposite ends thereof to another one of the opposite ends, fitted undetachably into and around the vapor inlet port at the one of the opposite ends, and connected with the breather tube at the other one of the opposite ends; and a flow control valve accommodated inside the joint, and controlling a flow volume of the vapors flowing into the filler-port body from the breather tube. ## Claims ### Claim 1 A resinous filler port comprising: a filler-port body made of resin, and comprising: a nozzle insertion port through which a filler nozzle is insertable, a fuel supply port supplying a fuel supplied from the filler nozzle to a fuel tank by way of a filler tube, a vapor inlet port letting flow in vapors arising from the fuel and passing through a breather tube from a side of the fuel tank, and a tubular fit-in portion provided with the vapor inlet port; a joint made of resin, and formed to penetrate through from one of opposite ends thereof to another one of the opposite ends, fitted into and around the vapor inlet port at the one of the opposite ends, and connected with the breather tube at the other one of the opposite ends; and a flow control valve accommodated inside the joint, and controlling a flow volume of the vapors flowing into the filler-port body from the breather tube; wherein the joint comprises: an outer cylinder formed at the one of opposite ends of the joint and fitted around an outer peripheral face of the tubular fit-in portion that is located on a diametrically opposed inner side of the joint, an inner cylinder formed at the one of the opposite ends of the joint located on a diametrically opposed inner side of the outer cylinder by way of a clearance located on a diametrically opposed inner side of the tubular fit-in portion and guiding a movement of the flow control valve, and a breather-tube connector portion formed at the other one of the opposite ends of the joint and fitted into the breather tube; and wherein: the tubular fit-in portion is inserted into the clearance between the outer cylinder and the inner cylinder, the tubular fit-in portion comprises at least one locking boss on the outer peripheral face to fix the joint around the vapor inlet port, the joint comprises at least one dent or through-hole engaging with the locking boss to fix the joint around the vapor inlet port, and penetrating through the outer peripheral face of the joint, the resinous filler port further comprises a seal member interposed between an outer peripheral face of the inner cylinder and an inner peripheral face of the tubular fit-in portion, and the seal member is arranged at the clearance between the outer cylinder and the inner cylinder. ### Claim 2 (depends on 1) The resinous filler port according to claim 1, wherein: the flow control valve is movable in an interior of the joint in a distribution direction of the vapors in compliance with a pressure of the vapors, and controls a flow volume of the vapors in compliance with a position thereof in the distribution direction; and at least some of a movement range of the flow control valve is located on a diametrically inner side of the tubular fit-in portion. ### Claim 3 (depends on 1) The resinous filler port according to claim 1 further comprising a cap attached to an opening at the one of opposite ends of the joint to inhibit the flow control valve from falling off from the opening at the one of the opposite ends of the joint, wherein: the joint, the flow control valve, and the cap make a unit to be fitted into and around the vapor inlet port. ### Claim 4 (depends on 1) The resinous filler port according to claim 1, wherein: the joint is fitted into and around the vapor inlet port by locking. ### Claim 5 (depends on 1) The resinous filler port according to claim 1, wherein: the seal member is disposed in an axial fit-in range between the tubular fit-in portion and the outer cylinder. ### Claim 6 (depends on 1) The resinous filler port according to claim 1, wherein: the outer cylinder comprises the at least one dent in an inner peripheral face thereof to fix the joint around the vapor inlet port. ### Claim 7 (depends on 1) The resinous filler port according to claim 1, wherein: the outer cylinder comprises the at least one dent in an inner peripheral face thereof to fix the joint around the vapor inlet port.
