(Effect of the invention) When skiing, when adjusting the size of the safety binding for skis and ski boots of the present invention, manually lift the handle part of the lever protruding from the rear wall of the housing part of the binding body and move it upwards. When swiveled, the rack plate pivotally attached to the lever by the connecting pin slides vertically upwards to allow the protruding part of the rack plate to come out from the recessed part of the board, and the fixing of the fastener body is released. Then, the guide rails on the mounting base allow it to move back and forth freely, so if you adjust the position of the binding according to the size of the ski boot and release the handle from the handle at the specified position, the lever will move downward. The protruding portion of the rack plate fits into the recessed portion of the board, and the fastener body can be automatically and easily fixed to the mounting base.

Also, the head of the lever is always pressed backward by the spring receiving plate by the restoring force of the compression spring, so the lever is pressed downward and fixed when you release your hand from the handle. It won't get stuck. The pressing force applied to the lever can be adjusted by the strength of the repulsive force of the compression spring and the height of the protrusion of the rack plate.

Also, since the lever is projected rearward from the opening in the rear wall of the housing of the binding body and is stored between the ski and the binding, the lever may contact the snow surface during sliding. Since it does not exist, it has the effect of preventing the accidental accident such as the binding of the binding being released when skiing, and the ski shoe may come off and fall or be injured.
