ABSTRACT:
A skateboard includes a board body having a bottom provided with a base having a bottom provided with two opposite wheel seats. Each of the two wheel seats includes a wheel axle for mounting a roller. The wheel axle of each of the two wheel seats has a center located at a height different from that of a center of the respective wheel seat, thereby forming an eccentric state, so that each roller has independent horizontal and vertical displacement, thereby forming a balance effect, so that the skateboard can be moved in a stable manner.
