Abstract:
1. A differential comprising: a differential case having a first side boss portion and a second side boss portion; a first side gear and a second side gear; a plurality of pinion gears; a first spring interposed in a compressed state between a surface of the first side boss portion and a corresponding surface of the first side gear, the surfaces opposing each other in an axial direction of the first side gear; a second spring interposed in a compressed state between a surface of the second side boss portion and a corresponding surface of the second side gear, the surfaces opposing each other in an axial direction of the second side gear; a plurality of pinion shafts, each of which is inserted from outside of the differential case, extending through a center hole in a corresponding one of the plurality of pinion gears and a corresponding through-hole provided in the differential case; and a pinion shaft holder that is arranged in a space surrounded by the plurality of pinion gears, and has a plurality of through-holes into each of which an axial end portion of a corresponding one of the plurality of pinion shafts fits, wherein: the first spring applies a preload for pushing the first side gear against the plurality of pinion gears; the second spring applies a preload for pushing the second side gear against the plurality of pinion gears; and recessed portions are provided on the pinion shaft holder and are configured to avoid interference with an auxiliary tool that keeps one of the first spring and the second spring in the compressed state.
