An apparatus including a canister and an accessory component associated with the canister. The canister may be filled with an adsorption material for adsorbing fuel vapor generated within a fuel tank. A communicating pipe extends downwardly from a housing of the accessory component for communication with the canister. An engaging protrusion is provided on an outer peripheral surface of the housing. An outer peripheral portion of an upper portion of the canister includes a wall portion for engagement with the engaging protrusion.

Apparatus having a canister and a component associated with the canister

A canister includes a canister case having an adsorbent chamber, an adsorbent housed in the adsorbent chamber of the canister case, a filter disposed between the adsorbent chamber and a port mounted on an end wall of the adsorbent chamber, and a tentative filter engaging projection provided in the adsorbent chamber. The filter is loosely fitted within the adsorbent chamber and then welded on the end wall of the adsorbent chamber. The tentative filter engaging projection tentatively holds the filter loosely fitted within the adsorbent chamber in a welding step of the filter.

Canisters

One aspect according to the present disclosure includes a first coupling device and a second coupling device. The first coupling device can mechanically couple the canister and the accessory component to each other. The second coupling device can couple the canister and the accessory component to allow flow communication with each other. The second coupling device is operable in conjunction with the operation of the first coupling device.
