Abstract

A bushing for a fan assembly includes a through hole longitudinally defined through the bushing for receiving therein a journal of the fan assembly and grooves each longitudinally defined in an inner periphery defining the through hole to communicate with the through hole. The grooves are able to collect residue arising from friction between the journal and the inner periphery of the bushing so that rotation of the journal is not hindered.
