An internal gear having a differential gear device fixed to a first input shaft, a sun gear integrated with a second input shaft, and a planetary gear meshing with the internal gear and the sun gear. The planetary gear is rotatably supported and is composed of a carrier spline-coupled to the output shaft, and a braking device of the differential gear device is an annular plate fitted to the outer peripheral surface of the carrier so as to be axially movable, A large number of carrier-side annular brake plates mounted only between the annular plate and the case so as to be movable only in the axial direction, a brake plate isolation spring interposed between the annular plate and the case, and the same isolation. In a tracked vehicle composed of a brake plate pressure contact hydraulic piston interposed between the annular plate on the opposite side of the spring and the case, via a brake plate cooling oil passage provided in the case and the output shaft. Supplied An oil hole for guiding a part of the cooling oil to the annular brake plate on the carrier end side is provided in the spline coupling portion of the carrier and the output shaft so as to penetrate the output shaft and the carrier in the radial direction. Braking device for differential gears of tracked vehicles.
