LIQUID TRAP STRUCTURE OF CANISTER

摘要

The present invention relates to a canister for a vehicle having a liquid trap structure formed thereon, wherein fuel can be prevented from flowing into the canister, where activated carbon is arranged. The liquid trap part includes: an input port arranged so that gas in a fuel tank can move into the canister including activated carbon; an air port arranged so that external air can flow into the fuel tank to prevent the generation of the negative pressure of the fuel tank; a gas flow port to allow the gas in the fuel tank to pass before flowing into the input port; and a body having a space for the flow of the gas in the fuel tank and the external air by being sealed except for the lower part connected to the input port, the air port, and the gas flow port. The lower end of the body is formed in a slanted manner, the gas flow port is arranged in the low position of the lower end of the body, the air port and the input port are arranged in positions higher than the low position of the lower end of the body, and the air port and the input port are connected to the lower part of the body to protrude upward from the lower end of the body inside the body.
