Abstract
A roller skate includes a base for supporting wheels and a support for attaching to a boot. The base includes a hub and a pair of slots. The support includes a pair of extensions extended downward for slidably engaging with the side portions of the base and for guiding and limiting the support to move up and down relative to the base. A shaft is secured to the extensions and slidably engaged in the pair of slots for limiting the up and down movement of the support relative to the base. A spring is engaged between the base and the support for cushioning the support.
