To generate a braking force. The braking pad 213 is not configured to rub against the ground, but rather to generate friction with the roller 209.

Here, the coupling structure between the components of the inline skate 200 will be described in more detail with reference to FIG. 4.

First, the fixing frame 203 extends to a predetermined height in a vertical direction on both sides of the base plate 203a and the base plate 203a for coupling with the boot 201, and the rear and front roller frames ( A side plate 203b is provided for providing the engaging means of 205 and 207, and a plurality of pinholes 203c are formed in the side plate 203b for engaging the rear and front roller frames 205 and 207.

The rear roller frame 205 and the front roller frame 207 are identical in themselves. However, the rear roller frame 205 is installed in the form of extending downward from the fixed frame 203, the front roller frame 207 is installed in the form of extending downward from the fixed frame 203. There is a difference in points.

The rear roller frames 205 are installed at equal intervals on the fixed frame 203, and the front rollers between the first and second rear roller frames 205 from the front of the rear roller frames 205. The frame 207 is installed. The rollers 209b installed on the front roller frame 207 are positioned in front of the rollers 209a respectively installed on the rear roller frames 205.
