PROBLEM TO BE SOLVED: To provide a wheel structure capable of oscillating an electric motor smoothly in an upward or downward direction even if a torque reaction force of the electric motor is received and further capable of restricting a reduction in function acting as a dynamic damper. SOLUTION: A wheel 1 comprises a wheel 14 rotatably supported at an axle shaft 10, an in-wheel motor 20 arranged in the wheel 14, a tire joint 22 connecting a rotor 20a of the in-wheel motor 20 to the wheel 14 in such a way that they can be eccentric to each other, link mechanisms 26, 27 for connecting a stator 20b of the in-wheel motor 20 with the axle shaft 10 and for supporting the in-wheel motor 20 against the wheel 14 in such a way that it can be oscillated in an upward or downward direction, a spring 28 attached between the link mechanisms 26, 27 and the axle shaft 10 to suspend the in-wheel motor 20, and a damper 30.
