PROBLEM TO BE SOLVED: To obtain a lighting skate board with functionality and amusement by using LEDs (light emitting diodes), and also to provide a half pipe. SOLUTION: The LEDs are embedded at an outer peripheral end on at least one of the upper, bottom, and side surfaces of the skate board, a power generator is attached to the shaft of each roller, and, then, the LEDs are lighted by power generated by the rotation of each power generator with the rotation of the rollers. A lighting control circuit is connected to the LEDs to control lighting such as continuous lighting or pattern flickering. Sensors are embedded in the sliding surface of the half pipe, and a course is set with the upper surfaces of the sensors as a passage designation point. Scores are added in response to the number of passages at passage designation points, and passage positions in the course, and displayed on a display board which is arranged in the main body of the half pipe. Display is performed in response to the passage designation points. COPYRIGHT: (C)2003,JPO
