| Zusammenfassung: | A heater for a canister includes a heater case embedded within an adsorption material and sealed at a top, and a heater core having a heat generation element and installed in the heater case. The bottom of the heater case is fitted into a heater retaining hole of a cap member in a hermetically-sealed state, for enabling the heat generation element and terminals of the heater core to be completely separated from the gas atmosphere containing the adsorbed fuel components within an activated carbon region. A leaf spring having a heat conductivity is arranged between an outside surface of one of a pair of strip-shaped ceramic plates constructing part of the heater core and an inner wall surface of the heater case, for retaining the heater core in place within the heater case and for permitting heat transfer from the heat generation element to the adsorption material.
