、吸着燃料の離脱装置。A pressure-operated on-off valve that controls the connection between the evaporated fuel adsorption device and the intake pipe has a first operating pressure chamber defined in the housing by a valve body and a diaphragm that holds the valve body, and a first operation pressure chamber that controls the opening of the valve body. It has a second operating pressure chamber defined in the housing by a diaphragm that holds a stopper that limits the position, and is located upstream of the carburetor throttle valve when it is in its fully closed position and downstream of it when the opening is over a certain small opening. A first operating pressure outlet port located on the side and a second operating pressure outlet port upstream of the first operating pressure outlet port are provided in the intake passage, and the first operating pressure outlet port is connected to the positive pressure is connected to the first operating pressure chamber of the on-off valve through a one-way delay valve that delays only the transmission of , an adsorbed fuel detachment device.
