This power transmission device (1) includes: a motor (2); a first planetary reduction gear (4) connected downstream of the motor (2); a second planetary reduction gear (5) connected downstream of the first planetary reduction gear (4); a differential device (6) connected downstream of the second planetary reduction gear (5); and drive shafts (8A, 8B) connected downstream of the differential gear (5). The drive shaft (8B) is arranged so as to pass through the inner diameter side of a rotor core (21) of the motor (2), the inner diameter side (the inner circumference) of a sun gear (41) of the first planetary reduction gear (4), and the inner diameter side of a sun gear (51) of the second planetary reduction gear (5). A pinion gear (43) of the first planetary reduction gear (4) is a stepless pinion gear, and a pinion gear (53) of the second planetary reduction gear (5) is a stepped pinion.
