。 A canister is provided with a valve having a purge pipe at one end and a fuel tank pipe, and an adsorption layer is provided in a container with the other end open. The canister is defined by a plate having an inlet at the other end and a perforated plate. A positive resistance characteristic thermistor heater is disposed in the suction chamber, and a circuit connecting this to a control unit consisting of a power supply, a relay section, a determination section, and an amplification section is provided, and the circuit is disposed on the upper end of the adsorption layer of the canister. 1. A fuel vapor release prevention device, characterized in that a control unit is connected to the temperature detection means, and is set so that power supply to the positive resistance characteristic thermistor heater is stopped when the temperature detected by the temperature detection means is below a predetermined temperature.
