An adsorbent container that stores fuel evaporative gas in a vehicle, a purge port provided downstream of the throttle valve in the intake passage, a purge passage that connects the adsorbent container and the purge port, and when the throttle valve is at the idling opening. A first port located upstream from the throttle valve and downstream from the throttle valve when the throttle valve is at a non-idling opening, a second port for extracting intake pipe negative pressure, and a purge port. The control valve includes a valve body for opening and closing the purge passage, a first chamber connected to the first port, and an intake pipe connected to the first chamber from the first port. A first diaphragm that moves the valve body in the opening direction when negative pressure is supplied;
A second chamber is connected to a port of the second chamber via an orifice, and when a negative pressure of a predetermined value or more is supplied to this second chamber, the second chamber moves toward the second chamber, and during this movement, the first A fuel evaporative gas emission suppressing device, comprising a second diaphragm that guides the diaphragm in the opening direction of the valve body.
