Abstract: A hydraulically operated power transmission apparatus transmits the output power from a power source at a selected speed ratio. The power transmission apparatus includes a casing having an opening in one end thereof, a base plate attached to the end of the casing in covering relation to the opening, the casing and the base plate jointly serving as a transmission case defining a closed space therein, a hydraulic pump having a pump drive shaft adapted to be operatively coupled to the power source, the hydraulic pump being disposed in the closed space, a hydraulic motor having a motor output shaft and drivable by a hydraulic pressure generated by the hydraulic pump, the hydraulic motor being disposed in the closed space, a pair of output shafts extending through the casing and the base plate, respectively, and disposed coaxially with each other, a differential mechanism disposed in the closed space and operable by the motor output shaft, the differential mechanism being coupled to the output shafts.
