PROBLEM TO BE SOLVED: To miniaturize a wheel structure having a drive, and to improve serviceability such as facilitation of attachment and detachment of a fastening means such as a bolt for fastening an axle hub and a disk wheel. SOLUTION: The axle hub 18 has a through hole, and fixes the disk wheel by the fastening means to be inserted into the through hole from an inside of a vehicle width direction. A motor 60 is provided inside the vehicle width direction of the axle hub 18 to transmit driving force to the axle hub 18. A motor housing 20 covers a motor 60. The motor housing 20 is provided with recessed parts continuing from a position facing the fastening means toward an outside of a radial direction of the axle hub 18. A stator 28 is fixed to the motor housing 20. A rotor 26 is rotatably provided inside the radial direction of the stator 28, which is provided with recessed parts in the part facing the recessed parts of the motor housing.
