    Abstract: A first electromagnetic valve includes a suction port that communicates with a purge pipe and sucks vaporized gas from a canister, a discharge port that communicates with a first purge pipe and discharges the vaporized gas to a downstream side of a throttle, a branch port that communicates with second purge pipes to which a second electromagnetic valve is attached and causes the vaporized gas to branch off to an upstream side of a compressor, a branch passage that diverges into and communicates with the suction port, the discharge port and the branch port. The branch passage includes a chamber having an inner diameter larger than each inner diameter of the ports.
