  • Publication number: 20240075769
    Abstract: A wheel mechanism includes a fixing base, a wheel base, a wheel, a fixing tube and a gasket. The gasket is disposed around the fixing tube to prevent the wheel with the wheel base from moving up and down. The upper gasket may be disposed between the fixing base and the wheel base to prevent the fixing base and the wheel base from colliding with each other to generate noise. The lower gasket may be disposed between the wheel base and the fixing tube to prevent the wheel base and the fixing tube from colliding with each other to generate noise. Further, when the wheel base is pivotally connected to the fixing base by the rotating shaft, the invention may selectively dispose at least one resilient member between at least two of the fixing base, the wheel base and the rotating shaft to prevent the wheel from shimmying.
