摘要： A differential includes a pinion shaft holder, a differential case, a first side gear, a second side gear, a first spring and a second spring. The differential case includes a first side boss portion and a second side boss portion. The first spring is interposed between the first side boss portion and the first side gear. The second spring is interposed between the second side boss portion and the second side gear. A recessed portion is provided on the pinion shaft holder and is configured to avoid interference with an auxiliary tool. The auxiliary tool maintains one of the first spring and the second spring in the compressed state.

摘要： An oil seal for sealing a hollow rotary shaft in a power transmission apparatus, wherein the rotary shaft is formed with an internal flow passage through which oil flows and constituted such that the oil flies out as the rotary shaft rotates, including: a fixed portion that is fixedly attached to a case of the power transmission apparatus; a seal portion that seals the rotary shaft at a position that is axially offset position from the fixed portion and allows the rotary shaft to rotate; and a radiator portion that is formed from a metallic material between the fixed portion and the seal portion, receives the oil that flies out as the rotary shaft rotates, and dissipates heat generated by the seal portion by exchanging heat with the oil.
