Patent abstract
A canister is taught that includes a container 10 containing granular adsorbent materials 30 that can adsorb fuel vapor generated from a fuel tank, and a plate-shaped dividing member 40, 45, 48, 65 and 72 that is disposed in the container 10 in order to carry the adsorbent materials 30. The dividing member 40, 45, 48, 65 and 72 is formed with a large number of elongated ventilating holes 60 and 68 for flowing the fuel vapor. Each of the ventilating holes 60 and 68 has an opening length 60L larger than a length 30L of the adsorbent materials 30 and an opening width 60w that can restrict passage of the adsorbent materials 30.
