Abstract:
1. A differential gear comprising: a ring gear being meshed with a drive pinion to be connected to an engine, with a case mounted on the ring gear; a plurality of input-side blocks partially fitted into grooves formed on the inner surface of the case; and two output-side cams being capable of clamping the blocks so that the inner surfaces of the cams can slip relative to the blocks and rotate independently due to the friction with each block, and being connected to the left and right drive wheels respectively; wherein the outer surface of one of the output-side cams is formed with recesses, the case is formed with through holes on a sidewall of the case at positions corresponding to the recesses, an annular member is placed around an outer cylindrical side of the case so as to be capable of moving, and projections are formed on the annular member so as to be capable of being inserted in and pulled out from the recesses through the through holes, and wherein the outer surface of the one of the output-side cams is provided with an extending portion that extends backwards, and the recesses are formed in the extending portion.
