PROBLEM TO BE SOLVED: To cope with both of wind throb noise and wind noise. SOLUTION: A sunroof device has a variable deflector 3 provided so as to freely rise and fall on an opening 2 provided on a roof 4, a vehicle speed sensor, a vibration sensor 11 for detecting vibration generated in a cabin of a vehicle 1, and an electronic control circuit 20, and is constituted so that rise and fall of the variable deflector 3 is controlled with two or more thresholds based on functional evaluation which a human body feels based on output for detecting the wind throb noise which becomes fluid resonance sound from a vehicle speed output of the vehicle speed sensor and the vibration sensor 11 by the electronic control circuit 20 and the output for detecting the low frequency vibration frequency of≤100 Hz generated in the cabin of the vehicle 1.
