Abstract: A motor casing of a ceiling fan has two pairs of lugs extending radially inward from the periphery thereof and the motor casing encloses the motor of the ceiling fan. A frame fixedly connected to a ceiling and has a flange to which two positioning devices are connected. Each positioning device has two support portions extending radially inward therefrom and each support portion has a slot. A resilient member connected to each support portion and is engaged between the two lugs corresponding to the positioning device so that the assembler can easily connect the motor casing and the frame without using bolts.

Abstract: A collar of a ceiling fan is composed of a plurality of sectors and each sector has a protrusion extending from a top thereof and a recess defined in an outside thereof. A resilient member is connected to each sector and includes a first portion having an aperture for receiving the protrusion, and a second portion which is a triangular member including two inclined sides. The resilient member is engaged with the recess of the sector corresponding thereto. The blade bracket has an end block which is engaged with the recess corresponding thereto and compressed by one of the inclined sides of the resilient member.
