PROBLEM TO BE SOLVED: To provide a pair of inline skates, answering body engineering, preventing a motion disability, having a braking function, achieving vibration prevention and powerful acceleration, assisting automatic correction at any time, and having a function of preventing falling to the ground. SOLUTION: The structure of the inline skates provides a cushion, a roller with a ratchet on its side and a pawl assembly. By pressing down the weight, the roller with the ratchet on its side engages the pawl assembly, which stops the roller with the ratchet on its side from rolling in single direction.
