In a parallel-axis differential, at least three pairs of planetary gears are rotatably receiving in a housing. At least three pairs of the planetary gears are arranged in a circumferential direction at intervals. The intervals are different from one another. Each pair of the planetary gears are in engagement with a pair of side gears respectively and also in engagement with each other. A large window opening is formed in a part of a peripheral wall of the housing which part corresponds to large one of the intervals. The large window opening is adapted to allow the passage of lubricating oil.
