An output gear of the differential apparatus includes a gear member and an operating member capable of being integrally rotatably engaged with the gear member via the cam portion. The cam portion includes a gear protrusion on the gear member, an operating protrusion on the operating member, and cam surfaces respectively provided on opposing surfaces of the gear protrusion and the operating protrusion. A corner portion on a tip side of at least one of the gear protrusion and the operating protrusion is provided with a retreating portion.

Methods and systems are provided for making and using a differential locking gear for locking a differential gear assembly that a first side gear connected to a first axel and a second side gear connected to a second axel. The differential locking gear has a first side with teeth configured to simultaneously mesh with first side gear teeth of the first side gear. The differential locking gear also has a second side with teeth configured to simultaneously mesh with second side gear teeth of the second side gear. The teeth of the differential locking gear that simultaneously mesh with the first and second side gears causes the first and second side gears to rotate in unison, thus locking the differential gear assembly.

The present invention provides a differential and a moveable power tool that has this differential. The differential comprises an input mechanism, an output gear, a first transmission component and a second transmission component. The input mechanism comprises a main input end and an auxiliary input end. When meshing of the output gear and a main input mechanism fails, the first transmission component and the second transmission component engage, and the second transmission component in said engaged state drives the first transmission component to rotate in a predetermined direction, so that the auxiliary input end inputs movement to the output gear. The differential provided by the present invention can guarantee the effectiveness and stability of movement transfer, and reduces the occurrence of slippage.
