An elastic truck for roller skates includes two brackets being located on center top portion of a front and a rear beams, respectively, and shaped like a bowl having their recess surfaces facing upward, two bosses having respective flanges near top portion, being integrally formed to the underside of the baseplate facing downwardly with one boss located behind the front beam and the other one located before the rear beam, respectively, and two semispherical elastic balls having respective circular grooves close to top portion thereon and respective blind holes at center portions therein. Wherein when a skater stands on the baseplate or when skater is making turns and jumping, the elastic balls and the blind holes will deform to absorb the vibration caused by such movement to maintain stability for skater.
