Abstract
A canister valve device for a vehicle that is equipped with a shutoff valve device connected to a pipe providing a passage for air to flow to a canister and selectively opening and closing the passage of the pipe, may include a diverging channel diverging from the passage of the pipe to a position where the shutoff valve device is positioned to provide a passage for a portion of air flowing to the pipe; and a check valve device positioned in the diverging channel, closing when the shutoff valve device closes, and opening when the shutoff valve device opens so that air is distributed to the pipe and the diverging channel, whereby negative pressure applied to the shutoff valve device is configured to be reduced by flow of the air.
