A slider includes a main board (1) movable on a snow ground (S), and a brake plate (2) mounted on the main board (1) and protruding outward from the main board (1) to face the snow ground (S). The brake plate (2) is formed with a shovel portion (5) extended toward the snow ground (S). Thus, the shovel portion (5) of the brake plate (2) is inserted into the snow ground (S) to provide a braking effect to the main board (1).
