Abstract
A canister for use in an evaporative emission control system of an automotive vehicle is provided which includes a box-like casing, an inlet port formed in one end wall of the casing through which fuel vapors generated within a fuel tank are drawn into the canister, and a plurality of vapor-adsorbing passages each of which is filled with activated carbon and has a given length through which the fuel vapors drawn through the inlet port flow. The vapor-adsorbing passages are all arranged within said casing in parallel to each other. This arrangement allows the casing to be of a flat shape which facilitates easy installation of the canister within a flat space around a fuel tank.
