An ejector for vaporized fuel gas recirculation devices is provided. The ejector for vaporized fuel gas recirculation devices reduces the number of elements equipped in a vehicle and an ejector mounting angle is adjusted to be suitable for a layout environment of the vehicle. Accordingly, a mounting cavity of the vehicle is more efficiently designed. When an intake pressure of an intake manifold is reduced a base component is moved in a direction toward a first nozzle component, and a region of the base component except an aperture closes the first nozzle component.
