An evaporation control apparatus is provided that reliably suppresses the emission of fuel components into the atmosphere. The evaporation control apparatus has a canister 2 and a control valve 20 that are configured as a unit to be disposed within the fuel tank 1 so that the connection path between the canister 2 and the control valve 20 is completely enclosed within the fuel tank 1. Therefore, fuel components are prevented from permeating the hoses and joints connecting the canister 2 and the control valve 20. In the unlikely event that fuel components should permeate the case body 20A of the control valve 20, emission of the fuel components into the atmosphere will be suppressed.

1. An evaporation control apparatus adapted to be arranged in a fuel tank of an internal combustion engine and coupled to a suction system of the internal combustion engine, said evaporation control apparatus comprising:a canister containing an adsorbent that temporarily adsorbs fuel vapor generated within the fuel tank of the internal combustion engine; and a control valve fluidly coupled to said canister to supply fuel vapor from the fuel tank to said canister when pressure within the fuel tank exceeds a prescribed pressure, said canister and said control valve being configured as a unit to be disposed within the fuel tank.
