SOLUTION: A skater is provided with wheels 3 and 11 at the front and rear sides of a board 6 and the front wheel 3 is steered by a handle. The skater is also provided with a fixing baseboard 14 which is attached to the side surface of at least one of the front and rear wheels 3 and 11 so as to be freely attachable/detachable in parallel with the wheel 3, a mobile baseboard 18 which is supported so as to be rotatable in the circumference of an axis being in parallel with the axis of the wheel 3 in the fixing baseboard 14, a transmission roller 15 which is attached to the mobile baseboard 18, and is brought into pressure contact with the wheel 3 and the driving motor 17 which drives the transmission roller 15 via a power transmitting unit 16 and which is driven and controlled by a mounted power source battery 10 and a control circuit 20a. The fixing baseboard 14 is optionally freely mountable/dismountable to/from the side surface part of the wheel 3.
