Abstract
The present disclosure provides a device for preventing the backward air flow of a reservoir tank for a vehicle, which may mount an backward air flow prevention tube extending to coolant on a connector of a reservoir tank to which a degassing hose is connected, and form an air collection slit hole communicating with an upper space of the reservoir tank in the upper portion of the tube to be openable or closable, thereby easily preventing the phenomenon in which the air within the reservoir tank flows back toward an engine, and easily collecting the air introduced from the engine side.
