Abstract
A wheel assembly includes: a wheel set unit including a wheel bracket and a wheel; and a brake unit including a brake element disposed between the wheel bracket and the wheel, a threaded member sleeved movably on the brake element, and a screw extending threadably through the threaded member, extending through the brake element so as to prevent movement of the threaded member on the brake element, and pushable downwardly such that the brake unit moves downwardly to press resiliently against the wheel, so as to arrest rotation of the wheel. Only a single tool is needed to be accessed to a lower end of the screw so as to adjust a distance between the brake unit and the wheel.
