PURPOSE: A roll over valve for vehicles is provided to facilitate installation and to maximize operation efficiency by being coupled with a rotary method. CONSTITUTION: A roll over valve(100) includes a valve body, a flange, a coupling device, and a stopper. A gas exhaust pipe is prepared in a top end of the valve body(110). The flange(120) is formed according to a top circumference of the valve body. The coupling device is formed according to a central circumference of the valve body. The stopper(150) is separated from the coupling device. The roll over valve is coupled with a rotary method in order to position a holding protrusion prepared on a valve injection hole of a fuel tank between the coupling device and the stopper in state a part of the valve body is inserted through the valve injection hole.
