Abstract
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.
