A wheel supporting and driving device, comprising a motor ( 20 ) fixed to a vehicle body ( 12 ), a drive gear ( 24 ) coaxially rotated by the motor ( 20 ), and a driven gear ( 30 ) coaxially and integrally rotated with a wheel ( 14 ) which are installed in a vehicle. The drive gear ( 24 ) is rotated by the motor ( 20 ) around a rotating center decentered from the rotating center of the wheel ( 14 ) in a direction crossing perpendicularly to the vertical direction. Also, the device comprises a suspension arm ( 40 ) connecting the drive gear ( 24 ) to the driven gear ( 30 ) in the state of the driven gear ( 30 ) reciprocatingly swingable around the rotating center of the drive gear ( 24 ) and a suspension spring ( 50 ) elastically connecting the wheel ( 14 ) to the vehicle body ( 12 ).
