PROBLEM TO BE SOLVED: To provide a fan heater system for a self-propelled marker vehicle, capable of suppressing consumption of the vehicle's battery by the fan heater while being in a simple configuration. SOLUTION: The fan heater system for the self-propelled marker vehicle includes: a vehicle 10; a marker device 20 comprising a display panel 21; an internal circuit 22 for marker display on the display panel, and a transformer circuit 23 to supply power to the internal circuit; a voltage generator 30 to supply power to the transformer circuit; and the fan heater 40 powered by the vehicle's battery 12, burning a fuel obtained from a vehicle's fuel tank 13 to heat air taken from a cab 14, and blowing the air into the cab, wherein the vehicle's battery is connected to the output of the transformer circuit via a charge control switch 50 to be charged by the transformer circuit. This simple configuration can charge the vehicle's battery and use the fan heater over an extended period of time without letting the battery run out. COPYRIGHT: (C)2009,JPO&INPIT
