Abstract
A castor includes an inner frame, an outer frame surrounding the inner frame, a plurality of buffering members mounted between the inner frame and the outer frame, a plurality of connecting ribs each connected between the outer frame and a respective one of the buffering members, and a plurality of connecting flanges each connected between the inner frame and a respective one of the buffering members. Thus, the buffering members are mounted between the inner frame and the outer frame and are compressed and deformed elastically to provide a shock absorbing and buffering effect to the castor when the castor is subjected to an external force or impact so as to reduce the vibration and pressure of the castor, thereby providing a comfortable sensation to a user when moving the castor.
