ABSTRACT:
A transmission device has holding slots provided in a boss portion thereof for holding engaging elements. A drive shaft has engaging recesses provided in an outer surface thereof for accepting partially the engaging elements to engage the transmission device with the drive shaft. The engaging elements remain urged against the engaging recesses of the drive shaft by a resilient member which is disposed radially of a boss portion of the transmission device for maintaining the engagement of the transmission device with the drive shaft. When the transmission device is overloaded, the engaging elements depart from the engaging recesses in the drive shaft, against the urging force of the resilient member, to cancel the transmission of torque from the drive shaft to the transmission device.
