Evaporated fuel treating device

An evaporated fuel treating device comprising a casing provided with an atmospheric port, wherein in the casing are provided in series a first adsorbent chamber housing adsorbent material, a space chamber not housing adsorbent material and a second adsorbent chamber housing adsorbent material,

• wherein said first adsorbent chamber, said space chamber and said second adsorbent chamber are disposed so that each of said chambers is positioned beside an adjacent chamber thereof,
• said first adsorbent chamber is disposed closest to the atmospheric port among said adsorbent chambers housing adsorbent material,
• at an end part of said space chamber on a side of said first adsorbent chamber is provided a first partition wall, and at said first partition wall is provided an opening part including a plurality of first openings only, said first openings being provided to position an end face on a bottom side of the first openings on a top side with respect to a center of said first partition wall in a top and bottom direction,
• wherein at an end part of said space chamber on a side of said second adsorbent chamber is provided a second partition wall, and at said second partition wall is provided an opening part including a plurality of second openings only, said second openings being provided to position an end face on a bottom side of the second openings on a top side with respect to a center of the second partition wall in the top and bottom direction, said second openings being formed on corresponding positions to said first openings, and
• a current plate is disposed so that one end of said current plate is positioned between the adjacent first openings and a surface and a rear face of the current plate are disposed along a top and bottom direction,
• wherein said first partition wall and said second partition wall are coupled with a coupling part, said coupling part having top-side coupling members formed in a shape of a plate, one end of said top-side coupling members being positioned between adjacent first openings in the first partition wall, the other end being positioned between the corresponding adjacent second openings in the second partition wall, and their surface and rear-faces being disposed along the top and bottom direction, and
• wherein at least a part of said coupling part comprises a current plate.
