ABSTRACT:
In a parallel-axis differential, a pair of sun gears are received in a housing in a coaxial relation. Also, at least a pair of planetary gears are received in the housing in parallel relation with the sun gears. The planetary gears of the pair are in engagement with the pair of sun gears, respectively and also in engagement with each other. A window opening for introducing lubricating oil is formed in the housing. Also, a fin for guiding the lubricating oil toward the window opening is formed on the outer surface of the housing. The fin is situated on the rear side of the window opening with reference to one rotating direction of said housing.
