In this power transmission device (1), a carrier (55) of a planetary reduction gear (5) and a differential gear case (60) of a differential device (6) are formed integrally. The carrier (55) of the planetary reduction gear (5) has support holes (651a, 551a) into which pinion shafts (54) are inserted. The pinion shafts (54) rotatably support a stepped pinion gear (53). The differential gear case (60) has shaft holes (60a, 60b) into which a shaft (61) is inserted. The shaft (61) rotatably supports a pair of bevel gears (62A, 62B). An axis (Y) that passes through the shaft hole (60a) and the shaft hole (60b) is set so as to avoid an overlap in the circumferential direction with the plurality of support holes (651a). The shaft (61) passes through the center of a virtual circle (Im) that links the plurality of support holes (651a).
