    Abstract: A hub and shaft securement arrangement is provided in which a spring clip having a loop portion and a tongue portion is arranged with an extension thereof between the loop and tongue portions disposed within a hub so as to be squeeze between flattened portions on it and an inserted shaft and with the tongue end in compressing relationship relative to the hub and the loop portion compressingly engaged between the other termination of the hub and a shoulder formed by a cross groove in the shaft. This clip arrangement, then, provides a securement means which may mount a fan hub on either end of a double shafted motor, and yet still may secure the hub to the shaft. It also provides a securement means which eliminates close tolerance requirements between various faces and shoulders on the hub and shaft.
