The present invention relates to a snowboard binding. The snowboard binding comprises: a base, a high back, a foot cover, a first wire, and a lever. The base comprises a plate attached to the snowboard, and side walls extending vertically from both sides of the plate. The high back is installed to pivot on the side wall in the rear of the base. The foot cover is installed at a distance from the upper front of the base. The first wire connects the high back to the base and foot cover. The lever is installed to pivot on the back of the high back and moves the foot cover as the length of the first wire connecting the lever to the high back varies depending on the pivot direction, wherein the first wire connected to the high back is connected to the side facing the pivot axis. Therefore, the foot cover and high back simultaneously fix the front and rear of boots as a result of the pivoting of the lever in the locking direction, and release of the lever is prevented.
