ABSTRACT OF THE DISCLOSURE A PTC thermistor device is disclosed which includes a heat generator containing a PTC thermistor unit, and heat radiators thermally coupled thereto. Each of the heat radiators includes a plate, one main surface of which is adhered onto the heat generator, and a number of fins integrally formed on the other main surface of the plate. Since the plates of the heat radiators are thermally coupled to the heat generator, respectively, heat generated by the PTC thermistor unit is radiated from the fins through the plates. Free ends of respective sets of fins form opening portions, and guide plates are disposed above and below the respective opening portions so as to prevent air from escaping through the opening portions. If the guide plates are movable guide plates and are moved, an opening degree of each opening portion covered by each of the movable guide plates is changed such that the temperature of warm air blown-out from an air outlet side can be adjusted or controlled.
