    • A canister for trapping a fuel vapor vaporized in a fuel tank has a casing defining an adsorption chamber therein, an adsorbent capable of adsorbing the fuel vapor and filled in the adsorption chamber and a flow regulation plate disposed in the casing. The casing has a fuel introducing port configured to introduce the fuel vapor from the fuel tank into the adsorption chamber, and an air communicating port communicating the adsorption chamber with the atmosphere. The air communicating port is formed on a side surface of the casing extending in a direction of gravitational force. The flow regulation plate disposed at an end of the adsorption chamber near the air communicating port and has an opening configured to communicate the adsorption chamber with the air communicating port. The opening is positioned above the air communicating port in the direction of gravitational force.
    • 用于捕获在燃料箱中蒸发的燃料蒸汽的罐具有在其中限定吸附室的壳体,能够吸附燃料蒸气并填充在吸附室中的吸附剂和设置在壳体中的流量调节板。 壳体具有将来自燃料箱的燃料蒸气引入吸附室的燃料导入口和将吸附室与大气连通的空气连通口。 空气连通口形成在沿着重力方向延伸的壳体的侧面上。 所述流量调节板设置在所述吸附室的靠近所述空气连通口的端部,并且具有使吸附室与空气连通口连通的开口。 开口位于空气连通口上方的重力方向。
