Abstract
A wheel resonator for reducing a resonance phenomenon inside a tire of a vehicle may include a plurality of wheel resonators mounted to a tire wheel. First and second wheel resonators of the plurality of wheel resonators are fixed with each other by a fastening part including a protrusion disposed on an end of the first wheel resonator penetrating through a hole disposed in an end of the second wheel resonator. An end portion of the protrusion has a size greater than a size of the hole. As such, quality of a wheel through more reliable noise reduction by making a wheel resonator in a manner of forming a fitting type fastening part in the wheel resonator itself and fixing the wheel resonator by ultrasonic welding can be improved.
