摘要
PURPOSE: A velocity display device of an inline skate is provided to allow a rider to confirm a moving velocity and a moving distance during riding the inline skate, and thus to allow the rider to check a suitable training time. CONSTITUTION: The velocity display device of an inline skate includes a radio transmitting device which detects revolution numbers of a roller of the inline skate and transmits a modulated data of the revolution numbers of the roller in a wireless form, a radio receiving device(44) which demodulates the modulated data transmitted from the radio transmitting device for controlling the modulated data to display a moving velocity, and a display portion(54) for displaying the moving velocity by control of the radio receiving device.
