A rollerboard for road-skiing includes a front wheel unit, a rear wheel unit, a support board, a support plate, a brake unit and a pair of poles. The support board has a plane portion one end of which is fixed with the rear wheel and a curvature portion which is arranged at the other end of the plane portion. The curvature portion has at a front end thereof a support shaft hole and is bent upwardly so as to surround the front wheel unit. The plane portion has a groove formed at the curvature portion side and which has a shock absorbing rubber attached thereon, and a hinge stopper piece at the rear wheel unit side. The front wheel unit is pressedly connected with a support shaft and a bearing cover having a slope of 10 DEG to 20 DEG inclined inwardly from a vertical line. A wheel support rod connected to the front wheel rotates at a bearing, and a bolt fixed to a front end of the support shaft and the rotating wheel support rod are connected via a spring so as to thereby control the rotation of the wheel support rod. The support plate is comprised of a foothold portion, first and second brake portions extended from an end of the foothold portion so as to brake the rear wheel and which serve as a mud guard, and a bent portion making contact to or separating from the other end of the foothold portion and which is connected to the curvature portion through a fixing bolt. The support plate is spaced from the support board, and a support rod to be inserted into a support board groove and a stopper piece to be connected via a hinge are arranged at a lower surface of the foothold portion. |
