<p>An inline skate includes a pair of vertical frames which are formed at left and right positions on the bottom surface of a frame to extend vertically so that wheels can be rotatably supported on the vertical frames. A plurality of left and right holes is defined in the vertical frames to pass through the vertical frames and to communicate with center holes defined in center portions of the wheels, such that axles are installed through the center holes and the left and right holes. Each of the wheels is installed either between the vertical frames or outside the vertical frames such that an inline skate version and a roller skate version of the inline skate can be selectively adopted. Each axle is configured so that the length thereof can be changed, and thereby, the interval between two wheels can be adjusted in a stepwise manner.</p> |
