A wheel including a substrate, a driving assembly, a fixing bracket, and a damper is provided. The driving assembly is disposed on the substrate to drive the substrate to rotate. The driving assembly and the damper are fixed onto the fixing bracket. The damper is disposed between the driving assembly and the fixing bracket, and the driving assembly is located between the substrate and the damper. The driving assembly has a first diameter, the damper has a second diameter, and the second diameter is greater than or equal to the first diameter. The wheel is disposed in a projector and may effectively reduce vibration and noise generated during the operation of the wheel, so as to mitigate a noise problem of the projector and increase a service life of the wheel.
