Abstract
Apparatus for releasably attaching a daisy print wheel to a splined shaft of an angular drive such that the print wheel can be driven in angular rotation with substantially no backlash. The apparatus comprises a splined hub fixed to the print wheel and slidably engageable with the splined shaft and a holder mounted on the hub for movement between a locking position in which the hub is locked on the splined shaft with interference fit and a released position in which the hub with the holder thereon is slidably removable from the splined shaft together with the print wheel. The hub includes a plurality of angular segments of cantilever formation which are pressed into the spaces between the splines on the drive shaft with interference fit by the engagement of the holder in its locking position. The holder is axially movable on the hub in traveling between the locking and release positions and is not normally removable from the hub.
