ガス漏出防止装置。 An activated carbon canister containing activated carbon stored inside a container is interposed in a fuel supply passage connected between the fuel tank side and the intake pipe side of the engine, and when the engine is stopped, evaporated fuel is transferred to the container of the activated carbon canister. The vaporized fuel is adsorbed onto the activated carbon to prevent it from leaking into the atmosphere, and when the engine is running, air is introduced from the outside into the activated carbon canister to separate the fuel from the activated carbon, and the released fuel is used as fuel in the engine. In the fuel evaporative gas leakage prevention device for supplying fuel to the intake pipe side, a plurality of activated carbon storage chambers are formed in the container of the activated carbon canister by air-permeable partition plates, and an insulating air chamber is provided between these activated carbon storage chambers. What is claimed is: 1. A fuel evaporative gas leakage prevention device characterized in that the evaporative fuel is introduced into the air chamber.
