An in-wheel motor drive unit (21) includes a motor portion A, a speed reduction portion B, and a wheel hub C. The speed reduction portion B includes outer pins (27) engaging with circumferences of curve plates (26a) and (26b) to generate rotation movements of the curved plates, and an outer pin holding portion (45) fixedly fitted in an inner diameter surface of a casing (22) holding the speed reduction portion B, to hold the outer pins (27) parallel to a rotation axis of a motor side rotation member (25). The outer pin holding portion (45) includes a cylindrical portion (46), a pair of ring portions (47) and (48) extending from axial both ends of the cylindrical portion (46) to radially inner side, and a pair of outer pin holding holes (47a) and (48a) provided at opposed positions of the pair of ring portions (47) and (48), and extending parallel to the rotation axis of the motor side rotation member (25) to hold the axial ends of the outer pin (27).
