Abstract
A canister has a housing whose one end is provided with a charge port and a purge port and whose other end is provided with a drain port and a heater. The housing is divided into a no-heat-application section on a charge port and purge port side and a heat-application section on a drain port side. The heat-application section is further divided into at least two spaces of a first space located on the drain port side and a second space located on a no-heat-application section side. The first space is filled with an activated carbon whose BWC is equal to or greater than 6 g/dL and less than 10 g/dL, and the second space is filled with an activated carbon whose BWC is 13 g/dL or greater. The heater heats whole of the heat-application section including the first space and the second space.
