Abstract: PROBLEM TO BE SOLVED: To reduce pressure losses and make almost uniform the distributions of the concentration and flow velocity of fuel mixed with air and finally released. SOLUTION: In an evaporated fuel injecting part 103, evaporated fuel 126 is separated into two streams, which reach evaporated fuel supply passages 103a and 103c. The cross-sectional area of a flow passage for air 120 is at its minimum at a mixing part 104. Nozzles 103b and 103d are provided in opposite positions on the interior wall of the mixing part 104. By causing the air 120 to flow at high speed in the mixing part 104, a negative pressure is created, causing the evaporated fuel 126 to be sucked from the nozzles 103b and 103d and injected into the mixing part 104 to cause the two streams to collide against each other. Since the air 120 flows into a portion where the two streams collide, the evaporated fuel 126 is entrained in and mixed with the air 120. The fuel 128 mixed with the air is released through a releasing part 106.  The releasing part 106 is shaped to extend radially about the mixing part 104.
