Abstract
An evaporated fuel treatment device for a vehicle is provided to suppress the flowout of evaporated fuel into atmospheric air. In the evaporated fuel treatment device, a communication chamber is formed in a fuel supply cap, allowing communication between a charge passage and the inside of a fuel tank in a closed state. In the communication chamber, a positive pressure adjusting valve is openable to supply evaporated fuel in the fuel tank to an evaporated fuel storage unit through the communication chamber and the charge passage, and a negative pressure adjusting valve is openable to supply atmospheric air to the fuel tank from the evaporated fuel storage unit through the communication chamber and the charge passage. An interlocking member is provided between the key cover and the negative pressure adjusting valve, and opens the negative pressure adjusting valve in an interlocking manner with an operation of opening the key cover.
