To provide an in-wheel motor driving device capable of preventing uneven wear of the inside of a decelerating part and contributing to labor saving in management of dimensional errors in assembling.
The in-wheel motor driving device 21 includes a motor part A, the decelerating part B decelerating the rotation of the motor part A to transmit the rotation to an output shaft 28, and a wheel hub 32 connected to the output shaft 28. The decelerating part B includes a cylindrical casing side member 45 extended from one end to the other end in the axial direction of the decelerating part and integrally formed with the one end and the other end; the output shaft 28 inserted through an inner hollow region of the casing side member; and two output shaft bearings 38a, 38b provided at the inner peripheries of both ends 45f of the casing side member respectively to support the output shaft 28 rotatably.
