LEAK PREVENTION STRUCTURE FOR VEHICLE

摘要

A low-cost leak prevention structure for a vehicle prevents liquid (4) in a container (2) from leaking outside if the vehicle (10) rolls onto its side. The leak prevention structure includes a gas passage (Id), formed inside a breather hose (1); a vent hole (Ie) at one end of the gas passage (Id) that is opened to the liquid chamber (3), and an exhaust hole (If) at the other end of the gas passage (Id) that is opened to an exterior of the container (2). The breather hose (1) includes an extending portion (Ia) which is positioned at an upper portion of the liquid chamber (3) and extends in a transverse direction of the vehicle (10). Accordingly, even when the vehicle (10) rolls onto its side, the liquid (4) does not leak out through the breather hose (1).
