Provided is a wheel drive device that can suppress decrease in coil temperature detection accuracy and that can improve responsibility in controlling an electric motor. This wheel drive device includes an electric motor (1) configured to drive a wheel; a wheel bearing configured to transmit a rotation of the electric motor to the wheel and configured to rotationally support the wheel; and an oil supply mechanism configured to guide a lubricating oil, radially outward from inside a main shaft of the electric motor (1), the lubricating oil being also used for cooling, and configured to inject the lubricating oil to coils (78) of the electric motor (1). A temperature detector (Sa) configured to detect a temperature of the coils (78) is disposed above a center (L1) of the main shaft and in a gap (´) between coils (78, 78) adjacent to each other in a circumferential direction. |
