Provided is a wheel drive device (100, 200) capable of increasing an allowable radial load. A wheel drive device (100, 200) of a certain aspect includes an internal gear (16) that is integrated with a casing (21, 22, 23); an external gear (14); an eccentric body (12a) that oscillates the external gear (14) ; an output flange (18) that is disposed at a side portion in an axial direction of the external gear (14); a pin member (32, 33) that is supported by the output flange (18) and penetrates the external gear (14); and a first main bearing (24) that is disposed between the output flange (18) and the casing (21, 22, 23). A wheel (50) is connected to the output flange (18). An inner diameter of an inner ring (24n, 26n) of the first main bearing (24) is larger than an inscribed circle diameter of the pin member (32, 33).
