Abstract
A device for locking a shaft in driving engagement within a sleeve including radially movable locking members mounted in the sleeve adapted to be held in a position to effect locked engagement with the shaft by an annular locking member operating to hold the spherical members radially in locking position relative to the sleeve. A helical spring is provided in engagement between the annular locking member and the sleeve and the spring includes first radial portions which engage the sleeve and second radial portions which engage the annular locking member in order to enable a large clearance to be provided between the sleeve and the annular locking member so that operation will not be adversely affected by accumulation of dirt.
