Abstract

An in-line roller skate having an improved sole plate structure includes a boot with an outer sole provided with a plurality of downwardly extending projections. Each projection is provided with a vertically oriented, elongated slot for receiving a bushing of an elastic plastic material for absorbing shock, and at least two pairs of mounting plates for clamping rollers between each pair pivotally-mounted to the corresponding projections. Each pair of mounting pairs secures two rollers at either end thereof. The mounting plates are arranged to be pairs of two and each pair of mounting plates is independently mounted to the projections of the boot. The in-line roller skate has good floor or ground adaptability and shock-absorbing effects.
