ABSTRACT:
A blower control resistor device includes a plurality of resistors leading to resistor terminals, and a plurality of connecting terminals joined with the resistor terminals by thermal fuses. The joint portions between the resistor terminals and the connector terminals are concealed by a cover or the like so as to prevent an authorized modification of the resistor device. Preferably, one of the thermal fuses which is connected with a connector terminal near a power supply has a lower-melting point than other thermal fuses.
