PROBLEM TO BE SOLVED: To provide a direct drive motor for achieving lubricant supply to rolling elements of a bearing without impairing the advantages obtained by employing a so-called bearing with flange formed by adding an attachment margin to an outer wheel of the bearing. SOLUTION: The direct drive motor has a bearing 3 having rollers 3a, 3b disposed between an outer wheel 31 and an inner wheel 32, a shaft 2 supported rotatably around an axial core by a casing 1 via the bearing 3, and a supply unit 7 for supplying a lubricant to the rollers 3a, 3b of the bearing 3. In the motor, an attaching surface 31b as one end side of the shaft direction in the outer wheel 31 is fixed to the casing 1 and the inner wheel 32 is fixed to the shaft 2, and the supply unit 7 is formed by connecting on the attaching surface 31b a first supply path 71 formed inside the bearing 3 and a second supply path 72 formed inside the casing 1 supporting the bearing 3 via the attaching surface 31b.
