To appropriately release the fixation of the leg, when a boarder is fallen down, and prevent occurrence of injury by comprising a snow board and boots, providing a permanent magnet or a magnetic body on the upper surface of the snow board, and providing a magnetic body or a permanent magnet on the bottom of the boots.

A snow board 20 is so constituted that the bottom face 21b of the snow board main body 21 becomes a sliding face, the top face 21a of the snow board main body 21 is made of a ribbon steel, and boots fixing positions 22, 23 are displayed as necessary. The boots 30 have a plate magnet 32 stuck on the bottom face 31. When the boots 30 are placed in a suited stance width on the boots fixation positions 22, 23, the magnet 32 is attracted on the top face 21a so as to be fixed at the position. When a boarder is fallen down in operation of the snow board and excessive load is applied thereon, the snow board 20 is so set that it is easily separated from the boots 30 so that the fixation of the legs is released.
