Abstract
The present invention includes a fuel vapor processing apparatus including a communication passage connecting between a first space and a second space each containing an adsorption material capable of adsorbing fuel vapor. The communication passage includes a dissipation delaying space capable of delaying dissipation or transmission of the fuel vapor between the first and second spaces. The communication passage further includes throttles positioned to oppose to each other across the dissipation delaying space.
