A folding skate board is provided to change direction or to move forward or backward, through the left and right movement of casters mounted on lower ends of front and rear boards by the rolling of anyone of boards. Directional casters are respectively installed on front and rear boards(10,10a). A connection shaft is connected to the front and rear boards(10,10a) to be able to move to the left and right. Protrusion pins having elastic bodies are mounted on the both ends of the connection shaft. A rotation portion encloses the elastic body mounted on the protrusion pin. Receiving portions having penetrating holes are formed at the ends of the front and rear boards(10,10a) to receive the rotation portion rotatably. A cover with an opening portion fixes the rotation portion. The connection shaft is made in a cylinder-shape.
