PROBLEM TO BE SOLVED: To provide an in-wheel motor drive device which has a high quality and improves durability by enhancing a lubrication performance in a motor part.SOLUTION: An in-wheel motor drive device 21 comprises a motor part A, a reduction gear part B, a wheel bearing part C, a casing 22 and a lubrication mechanism for supplying a lubricant to the motor part A and the reduction gear part B. A motor rotation shaft 24 of the motor part A rotationally drives a reduction gear input shaft 25 including eccentric portions 25a and 25b, the reduction gear part B reduces the rotation of the reduction gear input shaft 25 and transmits the rotation to a reduction gear output shaft 28, and the wheel bearing part C is connected to the reduction gear output shaft 28. The motor part A includes a stator 23a fixed to the casing 22 and a rotor 23b provided in the motor rotation shaft 24, and the motor part A includes a shield plate 70 for reducing stirring resistance of the lubricant caused by the rotation of the rotor 23b. |
