A differential locking device is for use with an all terrain vehicle for locking a pair of wheels together which are connected by a differential such that the wheels rotate together. The differential includes an inner case rotatably mounted within an outer case which is secured to the vehicle. A pair of inner pinions are mounted on a shaft for rotation within the inner case. The shaft extends transversely to an axis of rotation of the inner case. A pair of side gears are mounted on opposing sides of the inner case. Each side gear meshes with the pair of inner pinions such that rotation of one side gear in relation to the inner case will rotate the other side gear in an opposite direction in relation to the inner case. A pair of wheel axles are connected to and extend laterally from respective side gears for rotation with the side gear. The differential locking device is an annular plate having inner gear teeth extending radially inwards from an inner edge and outer gear teeth extending radially outward from a periphery of the plate. The inner gear teeth mesh with the inner case while the outer gear teeth mesh with one of the side gears. This will lock the side gear to the inner case and thus restrict rotation of both side gears relative to the inner case. The wheels are each connected to an end of the respective wheel axles which extend from the side gears such that the wheels rotate together.
