The present invention relates to constitution that auxiliary wheels are installed in a wing-shaped structure to stably maintain the balance of a skateboard. The skateboard is a riding instrument which enables a user to place their feet on a front board and a rear board by connecting the front and rear board separated back and forth from each other using a connector to enable the mutual twisting of the front and rear boards and by installing an inclined caster installed by inclining a caster having a wheel on the bottom surface of each board, thereby generating driving force and performing a direction change using the organic action between the twisting and the inclined caster. |
