<p>The present invention relates to a rollover check valve of a tank for an automobile. A conventional rollover check valve has a problem where a fuel is leaked into a guiding tube as a flap flowing up and down and from side to side touches a gas outlet in an inclined state when a vehicle body is tilted due to the flap moving to the left and right as well as up and down. Therefore, the rollover check valve of the tank for an automobile capable of preventing the fuel from leaking to the outside when a vehicle is turned over comprises: a rollover check valve case (100) having a gas outlet (110) on an upper portion and a float levitation chamber (120) with an opened floor on a lower portion; a supporting plate (200) blocking the floor of the float levitation chamber (120); a float (300) repeating up and down lifting to be returned by receiving a tensile force of a spring (310) installed between the supporting plate (200) and the float (300); a flap (400) installed by being placed on a flap installation unit (320), having a coupling unit (410) protruding on one side thereof; and a guide (500) installed on the upper surface of the float (300) forming a coupling groove (510).</p> |
