    Patent number: 10066721
    Abstract: A final drive device includes a housing and a final drive gear mechanism. The final drive gear mechanism is provided in the housing, and comprises a drive pinion and a ring gear meshed with the drive pinion and a differential gear mechanism. The differential gear mechanism includes a pinion rotatably supported by a pinion mate shaft, and a pair of side gears meshed with the pinion from both sides in an axle direction. The final drive device has a pinion carrier that is rotated in a direction around the axle integrally with the pinion mate shaft supporting the pinion, and which is secured to the ring gear. The pinion carrier is provided with a pinion housing unit that houses the pinion while permitting the pinion to rotate around its own axis. The side gears are fixedly located relative to the housing while being permitted to rotate around their own axes.
