ABSTRACT:
An improvement in the structure for mounting blades of a ceiling fan, characterized in that a motor comprises a bottom formed with a plurality of brackets each having a recess, the recess having an inner end which gradually decreases in size toward an outer end thereof, each of the blade having an inner end provided with a fixing member which extends outwardly and upwardly to form a tongue having an outer end which gradually increases in size toward an inner end of the tongue, the tongue being configured so that the outer end of the tongue has same size as the outer end of the recess while the inner end of the tongue has same size as the inner end of the recess thereby enabling the tongue 211 to fit into the recess from the inner end of the recess but not slide out of the outer end of the recess.
