| 主权项 | 1. A fuel vapor treatment device comprising: a casing comprising a gas passage formed in the casing; a granular adsorbent filled in the gas passage, the granular adsorbent serving to adsorb and desorb fuel vapor; and a desorption promoting structure to promote desorption of the fuel vapor in a central portion of a cross-sectional area of the gas passage as compared to an outer peripheral portion of the cross-sectional area of the gas passage, wherein the desorption promoting structure comprises a first granular adsorbent filled in the central portion of the cross-sectional area of the gas passage and a second granular adsorbent filled in the outer peripheral portion of the cross-sectional area of the gas passage, the first granular adsorbent having a grain size larger than a grain size of the second granular adsorbent. | ||
