To provide an in-wheel motor driving device capable of preventing vibration due to insufficient support rigidity in the case of newly providing an outer periphery engaging member holding part inside a casing.
A speed reducing section B of the in-wheel motor driving device 21 includes the casing 22; an input shaft 25 arranged inside the casing 22; eccentric members 25a, 25b connected to the input shaft 25; revolving members 26a, 26b carrying out revolving motion, with the inner peripheries mounted in a relatively rotatable manner to the outer peripheries of the eccentric members 25a, 25b; outer periphery engaging members 27 causing the rotating motion of the revolving members 26a, 26b; an output shaft 28 taking out the rotating motion of the revolving members 26a, 26b; the outer periphery engaging member holding part 45 mounted inside the casing 22 to support the outer periphery engaging members 27; and pressing members interposed while being elastically deformed between the internal wall of the casing 22 and the outer peripheral surface of the outer periphery engaging member holding part 45 to press the outer periphery engaging member holding part radially inward.
