  The present invention relates to a vehicle differential device, and more particularly to lubrication around a bearing that supports a differential case.

In this type of differential device, there is a case where the lubricating oil filled in the housing is supplied to each sliding portion such as a bearing by being lifted up by a diff ring gear fixed to the outer wall of the differential case. For example, Patent Document 1 proposes that a bearing receiving recess is formed with an oil receiving rib for receiving the lubricating oil scattered by the rotation of the diff ring gear, and a guide rib for guiding the lubricating oil received by the oil receiving rib to the bearing.

  By the way, when adopting a structure in which the lubricating oil scattered by the diff ring gear is received and guided to the bearing as in the conventional device, there is a problem that the mechanical loss of the diff ring gear due to agitation resistance increases.

  Therefore, in order to reduce the stirring resistance by the lubricating oil, it is conceivable to arrange a separate plate in the differential case. However, when the separate plate is simply disposed, the amount of the lubricating oil scattered on the oil receiving rib is likely to decrease, and in some cases, the lubricity may be lowered.
