Abstract
A fuel vapor gas purge system includes a passage forming member forming an intake passage of an internal combustion engine, a valve device being attached to the passage forming member and including a valve element switchable between an allowed state in which the vaporized fuel is allowed to flow into the intake passage and a blocked state in which the flow of the vaporized fuel into the intake passage is blocked, an electric circuit energized to generate a driving force to drive the valve element into the allowed state or the blocked state, a switch portion including an electric contact portion that causes the electric circuit to be in a conductive state when the valve device is attached to the passage forming member, and causes the electric circuit to be in a nonconductive state when the valve device is detached from the passage forming member.
