A safe roller skate structure comprises a base having four rollers 2 and a foot supporting pedal 1positioned lower than an upper periphery of each roller. The positioning of the pedal 1 relative to the rollers 2 provide the skate structure with a relatively low centre of gravity, thus making the roller skate safer to use. The pedal 1 includes the four integrally formed seats 10 for the mounting of each roller 2. The front rollers 2 may have a diameter half that of the rear rollers. The roller skate may be formed with three rollers 2 (see figure 5). |
