The invention provides an evaporated fuel processing device. The purpose of the present invention is to homogenize the temperature of a gas flowing in a space chamber between two adsorption chambers and the concentration of evaporated fuel. A housing (12) has a tank port (26) and a purge port (27) that communicate with one end side of a passage (24), and an atmospheric port (28) that communicateswith the other end side of the passage. A space chamber (44), which is not filled with the adsorbent (46), is provided between a second adsorption chamber (42) and a third adsorption chamber (43) provided in the passage. A first diffuser member (51) and a second diffuser member (52) are provided in the space chamber. The first diffuser member is formed in a tapered cylindrical shape having a largeopening portion that opens to the second adsorption chamber side and a small opening portion that opens to the space chamber. The second diffuser member is formed in a tapered cylindrical shape having a large opening portion that opens to the third adsorption chamber side and a small opening portion that opens to the space chamber.

    本发明提供蒸发燃料处理装置。谋求在两个吸附室之间的空间室流动的气体的温度和蒸发燃料的浓度的均质化。壳体(12)具有与通路(24)的一端侧连通的罐口(26)和吹扫口(27)以及与通路的另一端侧连通的大气口(28)。在设于通路的第2吸附室(42)与第3吸附室(43)之间设有不填充吸附材料(46)的空间室(44)。在空间室设有第1扩散器构件(51)和第2扩散器构件(52)。第1扩散器构件形成为具有向第2吸附室侧开口的大开口部和向空间室开口的小开口部的锥筒状。第2扩散器构件形成为具有向第3吸附室侧开口的大开口部和向空间室开口的小开口部的锥筒状。
