VAPORIZED FUEL TREATMENT APPARATUS FOR VEHICLE

摘要

A vaporized fuel treatment apparatus for a vehicle including a fuel tank for storing fuel therein with an openable and closable gas filler cap attached to the fuel tank. A vaporized fuel storage is operatively connected to a charge path through which the fuel tank communicates with the vaporized fuel storage and a purge path through which the vaporized fuel storage communicates with an intake system of an internal-combustion engine. A lid covers the gas filler cap to be opened and closed and is supported on a vehicle body. The vaporized fuel treatment apparatus is provided with a positive-pressure adjustment valve for opening when the internal pressure of the fuel tank reaches a predetermined pressure, allowing the fuel tank to communicate with the vaporized fuel storage. The positive-pressure adjustment valve opens when the lid is opened.
