PROBLEM TO BE SOLVED: To provide an in-wheel motor drive device capable of preventing a partial wear in the inside of a speed reducing portion, and saving power for management of a dimensions error generated when assembling.SOLUTION: An in-wheel motor drive device (21) is equipped with a motor portion (A), a speed reducing portion (B), a wheel hub (32), and a wheel hub bearing (33). The speed reducing portion has an input shaft (25), eccentric members (25a and 25b), revolving members (26a and 26b), an outer peripheral engaging member (27), an inside engaging member (31), a cylindrical casing side member (45) extending from an axial one end portion to the other end portion of the speed reducing portion and integrally forming the one end portion and the other end portion, an output shaft (28) inserted in an inner space area of the casing side member, and two output shaft bearings (38a and 38b) respectively provided on inner peripheries of both end portions (45f) of the casing side member to rotatably support the output shaft (28). |
