Abstract
Abstract In a releasable ski boot heel binding comprising a base to be attached to a ski, a casing having a boot heel engaging member at its front end, and a supporting member mounted to the base and pivotably connecting the casing, a cam member is swingably connected to the front portion of the supporting member. The cam member is urged and press-fitted to a transverse pin, which is connected to the front portion of the casing, by a depressing spring. The cam member has a dented portion in which normally the transverse pin engages and a protruded portion against which the transverse pin acts to force back the cam member.
