ABSTRACT:
A fuel vapor treatment device adapted to prevent evaporative emission from an automotive vehicle has a casing formed of a plastic and defines therein a space filled with a fuel vapor absorbent. An end wall is sealingly connected to a first end of the casing and provided with a first pipe through which fuel vapor is charged to the space, and a second pipe through which the fuel vapor within the space is purged. A cover plate is sealingly connected to a second end of the casing. A partition member is integral with the casing and disposed within the space of the casing to define first and second chambers. The partition member includes first and second partition walls that are parallel with each other and form a predetermined space therebetween. The partition member further includes a first lateral wall to connect first ends of the respective first and second partition walls, and a second lateral wall to connect second ends of the respective first and second partition walls. The first and second chambers are in communication with each other through a passage located near the second end of the casing. Additionally, a portion at which the end wall is connected to the first lateral wall is allowed to be exposed to an outside of the casing, thereby facilitating the inspection of a gas-tight seal between the first end wall and the partition member.
