PROBLEM TO BE SOLVED: To provide a skate board with enhanced travelling safety. SOLUTION: A pressure sensing part 8 is arranged at a position near the front part of the skate board 1. The part 8 is covered by an elastic material on the upper surface of the skate board 1, so as to easily sense pressure. A changeover switch is arranged on the lower surface of the skate board 1 so as to open/close a control circuit depending on whether the pressure sensing part 8 senses the pressure or not. When the part 8 senses the pressure, a driving motor drives wheels and travelling is started. COPYRIGHT: (C)2005,JPO&NCIPI
