The speed reduction unit (31) of the in-wheel motor driving device (10) includes an input shaft (32), an output shaft (41) coupled to a wheel hub (12) and extending in parallel with the input shaft, one or more intermediate shafts (35, 38) extending in parallel with the input shaft and output shaft, an input gear (33) coupled to the input shaft, an output gear (40) coupled to the output shaft, and a plurality of intermediate gears (34, 36, 37, 39) coupled to the intermediate shaft. The input gear, intermediate gears, and output gear are engaged with one another to form a driving force transmission path connecting the input gear to the output gear through the intermediate gears. At least one intermediate gear (37) of the intermediate gears has a diameter greater than the diameter of the output gear.
