The present invention, more specifically, comprises a deck which enables diagonal bending guided by a curving unit to bend diagonally; wheels each of which is fixed at the front and the rear of the lower side of the deck; and a supporting means on the right and left edges of the deck to prevent the rider′s back from bending. Especially, the supporting means comprises a block which is formed by extending from the lower part of the edge down and has a hollow rectangle shape; multiple blocking compartments comparting by crossing inside the block; an inserting groove in the center of the blocking compartments; a supporting edge which is made of a hard material of square shaped receiving force vertically and inserted into the groove by being unfolded; and a block cap which seals the lower part of the block after the supporting edge is unfolded. |
