ABSTRACT:
A connecting structure between a bicycle pedal and a cleat, comprising hooks pivotably supported by a pedal body for engaging and releasing the cleat, and an urging device for urging the hooks toward engaging positions. The object is to allow the cleat to be released with increased reliability when, for example, the cyclist falls over with his shoe becoming obliquely inclined relative to the pedal. A first cam mechanism is provided between each of the hooks and the cleat for causing the hook to pivot in a releasing direction when the cleat is inclined about a first imaginary axis extending substantially along a direction of pivotal movement of the hooks. The first cam mechanism includes a first pressed edge defined on one of the hooks and opposed to the cleat, and a first pressing edge defined on the cleat and opposed to one of the hooks for slidable contact with the first pressed edge. The first pressed edge and first pressing edge overlap each other as seen in a direction perpendicular to a tread of the pedal body.
