  "textContent": "Provided is an in-wheel motor drive device (21), including a motor part (A), a speed reducer part (B), a wheel bearing part (C), a casing (22), and a lubrication mechanism configured to supply lubricating oil to the motor part (A) and to the speed reducer part (B). A rotation shaft (24) of a motor in the motor part (A) is configured to drive an input shaft (25) of a speed reducer having eccentric portions (25a and 25b) to rotate. The speed reducer part (B) is configured to reduce a speed of rotation of the input shaft (25) of the speed reducer and transmit the rotation to an output shaft (28) of the speed reducer. The wheel bearing part (C) is connected to the output shaft (28) of the speed reducer. The lubrication mechanism includes an oil path (22b) in the speed reducer part (B), which is configured to discharge lubricating oil inside the speed reducer part (B) to the motor part (A), and an oil path (22f) in the motor part (A), which is configured to discharge lubricating oil inside the motor part (A) to an oil tank (22d) together with the lubricating oil from the speed reducer part (B) . The motor part (A) includes a partition plate (80) configured to guide the lubricating oil from the speed reducer part (B) to the oil path (22f) in the motor part (A).",
