A gaseous fuel discharge structure is used in a vehicle including an airtight cover disposed within a trunk thereof. The airtight cover covers a gaseous fuel containing tank. The structure includes an air introducing pipe and a gas discharging pipe both connected to the cover. If gaseous fuel leaks from within the tank, the structure is operated to discharge the gaseous fuel out of the vehicle. The air introducing pipe is provided with a fan. The air introducing pipe has an air intake flap while the gas discharging pipe has a discharge flap.

1. A gaseous fuel discharging structure for a vehicle having a trunk and a gaseous fuel containing tank disposed in a hermetic space defined within the trunk, said gaseous fuel discharging structure comprising:an air introducing pipe communicating with said hermetic space and extending to outside of the vehicle;a gas discharging pipe communicating with said hermetic space and extending to the outside of the vehicle;forced ventilation means disposed on at least one of said air introducing pipe and said gas discharging pipe for forcedly ventilating said hermetic space; andan opening/closing device disposed on each of said air introducing pipe and said gas discharging pipe,said opening/closing devices being held at a closed position to seal said air introducing pipe and said gas discharging pipe when said forced ventilation means is out of operation and, when said forced ventilation means is in operation, pivoted to an opened position so that any gaseous fuel leaked from said gaseous fuel containing tank into said hermetic space is forced out of the vehicle through said gas discharging pipe by fresh air flowing through said air introducing pipe into said hermetic space. 2. A gaseous fuel discharging structure for a vehicle, according to claim 1, wherein said hermetic space is defined by a sealing cover hermetically enclosing said gaseous fuel containing tank,said air introducing pipe and said gas discharging pipe extending outwardly of the vehicle from said sealing cover, said forced ventilation means comprises a fan to be actuated upon leakage of the gaseous fuel, and said opening/closing devices comprises flaps to be pivoted to the opened position by the flow of air produced by said fan. 3. A gaseous fuel discharging structure for a vehicle, according to claim 1, further comprising a floor plate provided for carrying an entrance of said air introducing pipe and an exit of said gas discharging pipe thereon, said floor plate having right and left side frames mounted thereon, one of said entrance and said exit being positioned outwardly of said left side frame, the other of said entrance a and said exit being positioned outwardly of said right side frame.
