ABSTRACT:
A fuel tank and a canister are connected to each other by a first evaporated-fuel passage and a second evaporated-fuel passage, and a valve chamber of a float valve separate from the fuel tank is disposed at an intermediate portion of the first evaporated-fuel passage. Thus, there is no limitation in the positional relationship between a filled-up liquid surface in the fuel tank and a valve seat of the float valve. Therefore, it is possible to reduce the vertical dimension of the float valve. Moreover, since the valve chamber is provided separately from the fuel tank, it is unnecessary to define an opening for mounting the valve chamber to the fuel tank.
