Abstract

PURPOSE:To suppress detection errors by installing a means for correcting disturbances of the terrestrial magnetism such as electromagnet near the bearing sensor. CONSTITUTION:A plurality of heat rays 22 constituting a rear defogger are buried in parallel in a rear windshield glass 21, and current is supplied to these. A rear shelf 23 is installed in the position opposing to this glass 21, and a nonmagnetic case 24 containing a bearing sensor is mounted near the central part above this. Also, an electromagnet 24 which corrects the disturbance in the terrestrial magnetism during the operation of the defogger is installed above this case 24. The electromagnet 25 is also housed in a nonmagnetic case 26 like the bearing sensor.
