Abstract
A shaft adapter for a fan motor has an elongated configuration with a fan motor shaft receiving socket portion provided at one end and a fan blade mounting shaft provided at the other end. By making a receptacle formed in the socket portion of a different diameter than the shaft, different diameter motor shafts and fan blade shaft receiving bores can be connected to one another. The adapter is preferably constructed from a rigid yet relatively soft material to facilitate cutting off of the shaft at a desired length for a particular installation.
