  "textContent": "A canister includes a charge port, a purge port, an atmosphere port, a main chamber, a sub chamber, activated carbon, and additional activated carbon. The sub chamber communicates with the main chamber. The atmosphere port is connected to the sub chamber directly or via an additional chamber. The activated carbon is stored in a main volume (Vmain) in the main chamber. The additional activated carbon is stored in a sub volume (Vsub) in the sub chamber. A ratio of a length L in a gas flow direction to an equivalent diameter D in a section perpendicular to the gas flow direction is 2 or more for the sub chamber. A ratio of a volume of the activated carbon stored in the main chamber to a volume of the activated carbon stored in the sub chamber (Vmain/Vsub) is more than 7 and equal to or less than 10.",
