The side frames (14) are attached respectively to the sides of the bottom board (10), and each side frame (14) has a top. The stepping frames are connected respectively to the side frames (14), and each stepping frame has an anti-slipping frame (15) and a side wing (16). The anti-slipping frame (15) is mounted securely on the top of a corresponding side frame (14) and has an anti-slipping member. The side wing (16) is connected to the anti-slipping frame (15) and extends toward a side opposite to the bottom board (12). Accordingly, the base (10) can fit with different running belts (20) with different widths and is versatile and convenient in use.</p> |
