An evaporated fuel treating device includes a chamber, closest to an atmospheric port, divided into first, second, and third compartments by a partition member having a peripheral wall and a separating wall. The first compartment has an adsorbent layer and one end in communication with the third compartment and another end in communication with a tank port. The second compartment communicates with the first compartment through a first communication portion formed at one end of the peripheral wall. One end of the second compartment communicates with the third compartment through a second communication portion provided in the separating wall, while the other end thereof is closed. The airflow resistance of a second filter covering one end of the peripheral wall and one end of the separating wall is higher than the airflow resistance of a first filter covering one end of the adsorbent layer. |
