<p>PROBLEM TO BE SOLVED: To provide a sealed differential device capable of sufficiently securing anti-abrasion performance and anti-seizure performance in which lubricating oil can be maintained clean. SOLUTION: This device is provided with a differential gear mechanism 3 comprising a differential case 5 in which lubricating oil is filled, a pinion gear 17, a pair of output side side gears 21, 23 connected to each other through the pinion gear 17 and disposed to face each other, a cone clutch 29, and a plug 33 and a seal ring 31 to prevent leak of the lubricating oil outside the differential case 5. Plural through holes are formed in an inner member of a two-layer plate cone member 27 for composing the cone clutch 29, and its outer member is magnetized, so that metal abrasion powder in the lubricating oil is attracted to purify the lubricating oil, and that differential motion is limited.</p> |
