Abstract
The present invention provides an evaporation fuel processing device including: a passage formed inside so as to allow a fluid to flow through the passage; a tank port and a purge port formed on one end side of the passage; an atmospheric air port formed on the other end side of the passage; and adsorbent layers filled with adsorbent which can adsorb evaporation fuel components, the adsorbent layers being provided in the passage, wherein a region which is constituted of three or more adsorbent layers and separating parts for separating the adjacent adsorbent layers, and in which a total volume of the adsorbent layers is set smaller than a total volume of the separating parts, is provided on an atmospheric air port side of the passage.
