PURPOSE: A charcoal temperature controller of a canister is provided to improve the fuel evaporative gas absorbing and removing performance by controlling the temperature of the charcoal received in a canister. CONSTITUTION: A charcoal heat sink has a main plate with many sub-plates and a fixing piece(33) protruded out of a housing(21). A radiator supported on the housing makes a movable piece(42) and the fixing piece exchange heat. A diaphragm(50) contracts and expands depending on the temperature of charcoal in the housing. An operating bar(60) hinge-coupled to a bracket(62) operates the movable piece. A motor-driven push rod(72) pushes the movable piece by the operation of a motor-driven valve(70).
