PURPOSE: A skateboard is provided to train the sense of balance by using a line of driving wheels installed on the lower center part, and to increase the capacity for locomotion of arms by using a stick attached to the skateboard. CONSTITUTION: In the skateboard(1) having a pair of driving wheels(3) on the front part and the rear part of a footboard(2) respectively, a line of driving wheels are installed on the center part of the bottom surface of the footboard, and a projection(5) is formed on the both sides of the footboard. The projection is drilled with an insertion hole(6) for holding a stick(4) used to advance the skateboard. The stick consists of a foldable rod(7) of different diameter. A hole(8) is formed on the upper end of the rod, and a hook(9) is formed on the lower end of the rod. When the rod is rotated across the angle of 90 degree, the hook of one rod is inserted into the hole of the other rod, thereby the rod is maintained in unfoldable state. When the hook is separated from the hole, the rod is folded. A handle(10) is provided on the longest rod, and a rolling plate(11) is provided on the shortest rod.
