摘要：
A fuel evaporation gas discharge suppressing device of an internal combustion engine includes a gas storage tank for storing a fuel evaporation gas in a communication passage for causing an air intake passage and a fuel tank in an internal combustion engine of a vehicle to communicate with each other in the communication passage. Control unit controls canister opening/closing unit, fuel tank opening/closing unit and gas tank opening/closing unit based on an internal pressure of the fuel tank. The control unit opens the canister opening/closing unit and opens the fuel tank toward the communication passage, and then opens the gas storage tank toward the communication passage when reducing the internal pressure of the fuel tank.
