A structure of inline skates is provided, the structure of inline skates includes a cushion device, a wheel with an annular ratchet wheel on its side, and a pawl assembly. By using the user's weight to press down the structure of present invention, the wheel with the annular ratchet wheel on its side engages the pawl assembly, which stops the wheel with the annular ratchet wheel on its side from rolling in one direction, and the wheel with the annular ratchet wheel on its side can roll in another direction. Thereby, the structure of inline skates is more ergonomic and exercise injuries can be prevented. In addition, a brake is provided for providing shock absorption and as a fulcrum to make more powerful acceleration. Besides, automatic support upright is also provided for avoiding tumbles.
