ABSTRACT:
A ski boot heel binding having a cam member slidably disposed within a bore formed in the lengthwise direction of a main body is disclosed, wherein the cam member is connected to the front end of a rotatably mounted unlocking lever. The unlocking lever has an inclined shoulder at the upper portion thereof against which a fulcrum pin bears and which is fixed relative to the main body, whereby when the rear end of the unlocking lever is lifted, the fulcrum pin slides down relative to the shoulder with the result that the fulcrum point of the leverage is shifted so as to retract the cam member in a straight line along the bore and displace the binding to the heel releasing position.
