PROBLEM TO BE SOLVED: To provide an evaporated fuel processing device capable of reducing blowing-through of evaporated fuel components to the outside.SOLUTION: The evaporated fuel processing device is equipped with adsorption chambers 35 and 37 filled with a first adsorbent 38 and a second adsorbent 39 to adsorb and desorb fuel components of the evaporated fuel. The first adsorbent 38 has larger capacity of effective pores for adsorbing and desorbing of the low boiling point fuel component(s) effectively than the second adsorbent 39. The first adsorbent 38 has smaller capacity of pores smaller than the effective pores and having larger butane adsorbing power than the effective pores and having smaller desorbing power than that of the second adsorbent 39. |
