ABSTRACT:
A wheel assembly has a swiveling shaft, a support member movably assembled with the swiveling shaft, an arresting member and wheels. The swiveling shaft includes a swiveling sleeve, a pressing element disposed on the swiveling sleeve, and a first gear bracket and a second gear bracket. The support member includes a rack with an opening, and a third gear bracket snapped in the opening, The arresting member is mounted on the rack. A first resilient element is provided between the arresting member and the rack. A second resilient element is provided between the arresting member and the third gear bracket. The wheels respectively pivot to the rack, and are limited at opposite sides of the arresting member. The pressing element limits rotation of the wheels, preventing deformation of the wheels thereby effectively stopping the wheels and lengthening lives of the wheels.
