Abstract:
Provided is an in-wheel motor drive device (21) including: a motor (28); a wheel bearing (53); and a speed reducer (38). The speed reducer (38) comprises: a speed reducer input shaft (Sin) including an input gear (34); a speed reducer output shaft (Sout) including an output gear (37); and an intermediate shaft (Sm) including a small-diameter intermediate gear (36) and a large-diameter intermediate gear (35). The large-diameter intermediate gear (35) has a circumscribed circle which is superimposed with a pitch circle of a plurality of rolling elements (42) of the wheel bearing (53) when viewed from an axial direction.
