PROBLEM TO BE SOLVED: To provide a vaporized fuel treatment device for reducing the blow-by quantity of vaporized fuel to be released from an atmosphere port into the atmosphere.SOLUTION: The vaporized fuel treatment device includes a tank port 3, a purge port 4, an atmosphere port 5, and a case 2. On the tank port 3 side in the case 2, a first storage chamber 6 is formed, and on the atmosphere port 5 side of the first storage chamber 6, a second storage chamber 7 is formed which has a smaller capacity than the first storage chamber 6. The first storage chamber 6 and the second storage chamber 7 are provided so as to be folded back via a space 8 formed therebetween. In the first storage chamber 6, an adsorbent room storing the crushed coals is arranged, and in the second storage chamber 7, a plurality of adsorbent rooms 13, 17 storing granulated coals and a space room 15 not storing adsorbent between the adjacent adsorbent rooms are arranged in series to each other. |
