A mount structure for a two-way valve for a fuel tank of a small boat for improving mountability of the two-way valve while ensuring strength of the deck. The interior space of the boat, which is formed of a hull and a deck, is provided with an engine, a fuel tank, and a duct. One end of the duct is attached to the wall surface of the deck with a mount member. The two-way valve is connected to the breather hose of the fuel tank, and attached to the mount member at one end of the duct from the interior space of the boat. The mount member is integrally provided with a mount pipe for the tube which opens the two-way valve outside the deck.

1. A mount structure for a two-way valve which is operatively communicating with a fuel tank of a small boat for venting the fuel tank to the atmosphere outside the small boat, said small boat having an interior space defined by a hull and a deck, said interior space having an engine, a fuel tank and at least one aerating duct for aerating the interior space of the boat to the atmosphere outside the boat, one end of the aerating duct being attached to a wall surface of the deck with a mount member, said mount member containing a two-way valve mounted in said mount member, said two-way valve communicating with the atmosphere outside the boat and a breather hose connecting the two-way valve to the fuel tank. 2. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the mount member is integrally provided with a mount pipe for a tube which opens the two-way valve outside the deck, and the mount pipe is opened outside the deck. 3. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the mount member includes a plate portion reinforced with a rib, a tubular duct mount portion integrally formed with a back surface of the plate portion and a mount portion integrally formed with the back surface for mounting the two-way valve. 4. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 3, wherein the mount member further includes a mount pipe integrally formed with the plate portion to penetrate from the back surface to the upper surface thereof for attaching a tube for opening the two-way valve to the outside. 5. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the mount member includes a duct mount portion connected to the end of the aerating duct. 6. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the breather hose is connected to a first connector portion of the two-way valve with a second connector portion of the two-way valve being connected to a mount pipe with a tube. 7. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the two-way valve is formed by combining two check valves with the breather hose being connected to a first connector portion and a first end of a tube being connected to a second connector portion with a second end of the tube being connected to a mount pipe of the mount member for opening outside the deck. 8. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein, when the fuel tank has a pressure higher than a predetermined pressure, the two-way valve discharges fuel vapor to the atmosphere. 9. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein when the fuel tank has a pressure lower than a predetermined pressure, the two-way valve permits air to flow into the fuel tank. 10. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 1, wherein the two-way valve is connected to the breather hose of the fuel tank for reducing the amount of fuel vapor generated in the fuel tank discharged to the atmosphere. 11. A mount structure operatively communicating with a two-way valve for a fuel tank of a small boat, comprising: a mount member;an aerating duct adapted for aerating an interior space of the boat to the atmosphere, one end of the aerating duct being attached to a wall surface of a boat deck with said mount member;a breather hose adapted to be operatively connected to the fuel tank;said mount member containing a two-way valve including a first connector and a second connector, said breather hose being operatively connected to the first connector;a tube including a first end operatively connected to the second connector of the two-way valve, wherein said tube includes a second end open to the atmosphere. 12. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein the mount member is integrally provided with a mount pipe for the tube which opens the two-way valve to the atmosphere. 13. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein the mounting member includes a plate portion reinforced with a rib, a tubular duct mount portion integrally formed with a back surface of the plate portion and a mount portion integrally formed with the back surface for mounting the two-way valve. 14. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 13, wherein the mounting member further includes a mount pipe integrally formed with the plate portion to penetrate from the back surface to the upper surface thereof for attaching the tube for opening the two-way valve to the atmosphere. 15. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein the mount member includes a duct mount portion connected to the end of the duct. 16. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein the mount member is integrally provided with a mount pipe for the tube for opening the two-way valve to the atmosphere for improving the mountability of the tube to the mount member. 17. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein the two-way valve is formed by combining two check valves with the breather hose being connected to the first connector portion and the first end of the tube being connected to the second connector portion and the second end of the tube being connected to the mount pipe of the mount member for opening to the atmosphere. 18. The mount structure of a two-way valve for a fuel tank of a small boat according to claim 11, wherein when the fuel tank has a pressure higher than a predetermined pressure, the two-way valve discharges fuel vapor to the atmosphere. 19.
