RELEASE RESTRAINING DEVICE FOR EVAPORATED FUEL

摘要

PURPOSE:To effectively restrain release of evaporated fuel from a fuel tank at feeding fuel oil without using a seal having problems in durability. CONSTITUTION:A first evaporated fuel passage 3 connects a canister C adsorbing evaporated fuel from a tank main body 1 to the tank main body 1, a second evaporated fuel passage 22 connects the inlet part 2a of a fuel feed pipe 2 to the tank main body, and the ventilation resistance of the second evaporated fuel passage 22 is set to be larger than the ventilation resistance of the first evaporated fuel passage 3.
