PROBLEM TO BE SOLVED: To provide a roller skate which can absorb vibration from the non-flat road when rolling and can reduce centrifugal force at a curve, and which is assembled from a small number of components and has a simple construction. SOLUTION: In the roller skate, a front wheel and a rear wheel are rotatably supported on the opposite ends of a skate board itself, respectively, while the interval between the front wheel and the rear wheel is made larger than the length of a skate shoe, and the thickness of the skate board is made thinner with the distance from the heel part of the skate shoe toward the opposite ends of the skate board, respectively.
