Abstract
A rolling wheel that moves more agile and at greater speed for a host object such as a skate is comprised of a ball roller, placed in a case and covered up with a casing lid to restrict the ball in the case, multiple holding wheel chambers provided on top of the case each accommodating a holding wheel; the ball roller when placed in the case maintaining a certain spacing with the case without contacting each other when held against by those multiple holding wheels by taking advantage of the directionless rolling of the ball roller.
