徴とする自動車用エバポシステムの配管構造。[Scope of Claim for Utility Model Registration] The vaporized gasoline in the fuel tank is guided to the canister and adsorbed to the adsorbent in the canister, and when the engine is running, a suction force is exerted from the engine side to the canister side due to the negative pressure effect to convert the vaporized gasoline to the canister. In an automobile equipped with an evaporation system that sucks outside air, a lower part of the canister is communicated with a first closed section of the vehicle body located below the canister through a communication member, and the lower part of the canister or the communication member is connected to the first closed section of the vehicle body located below the canister. A piping structure for an evaporative system for an automobile, characterized in that the piping structure is connected to a second closed section located at a higher position than the first closed section through a ventilation member.
