[Problems]To provide a wheel assembly allowing the elimination of an installation space for suspension element on the outside of a wheel and capable of satisfactorily damping and absorbing shock and vibration in the vertical direction. [Means for Solving Problems] Suspension element ( 70 ) is disposed, in a generally raised state, inside of a rim ( 11 ). The upper end of the suspension element ( 70 ) is connected to a first support member ( 50 ) mounted to a vehicle body. The lower end of the suspension element ( 70 ) is connected to a second support member ( 60 ) rotatably connected to the disk ( 12 ) on the wheel ( 10 ). The shock and vibration from the wheel ( 10 ) in the vertical direction are damped and absorbed by the suspension element ( 70 ). Also, a spring mechanism ( 30 ) and a flat bearing ( 40 ) are disposed in the wheel ( 10 ). The spring mechanism ( 30 ) is disposed between a rotating member ( 20 ) rotatably supported on the vehicle body and the rim ( 11 ) of the wheel ( 10 ). In the case the rotating member ( 20 ) is fixed to a brake drum, braking torque is transmitted to the wheel ( 10 ) through the spring mechanism ( 30 ). The flat bearing ( 40 ) is disposed between the rim ( 11 ) and the rotating member ( 20 ) and prohibits the axial movement of the wheel ( 10 ) relative to the vehicle body.
