## Abstract

A connecting structure between a bicycle pedal and a cleat is formed of hooks pivotably supported by a pedal body for engaging and releasing the cleat, and an urging device for urging the hooks toward engaging positions. 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 the pedal body tread.

## Claims

### Claim 1

A pedal for engaging a cleat having a front engaging portion and a rear engaging portion, said pedal comprising:
a pedal body having
a first hook for engaging said front engaging portion of said cleat;
a second hook for engaging said rear engaging portion of said cleat;
a pedal shaft for rotatably supporting said pedal body: and
a contact plate for contacting said cleat;
wherein said second hook is pivoted from a cleat engaging position to a cleat disengaging position by rotating said cleat about an axis of rotation while said cleat is in contact with said contact plate; and
cleat-movement restricting means provided between said pedal shaft and said first hook, said restricting means having a pair of stopper projections that are spaced apart from each other such that said front engaging portion is located between said projections when said front engaging portion is engaged with said first hook, said restricting means causing said axis of rotation of said cleat to be adjacent to said restricting means.

### Claim 2 (depends on 1)

The pedal of claim 1, wherein said stopper projections are formed by bending portions of said contact plate in a direction perpendicular to said contact plate.

### Claim 3 (depends on 1)

The pedal of claim 1, wherein said stopper projections are spaced apart from said first hook.

### Claim 4 (depends on 1, 2, 3)

A pedal as defined in one of claims 1-3, wherein a distance between said stopper projections increases with increasing distance from said first hook.

### Claim 5

A pedal for engaging a cleat having a front engaging portion and a rear engaging portion, said pedal comprising:
a pedal body having
a first hook for engaging said front engaging portion of said cleat;
a second hook for engaging said rear engaging portion of said cleat;
a pedal shaft for rotatably supporting said pedal body; and
a contact plate for contacting said cleat;
wherein said second hook is pivoted from a cleat engaging position to a cleat disengaging position by rotating said cleat about an axis of rotation while said cleat is in contact with said contact plate; and
cleat-movement restricting means provided between said pedal shaft and said first hook, said restricting means having a pair of stopper projections that are spaced apart from each other such that said front engaging portion is located between said projections when said front engaging portion is engaged with said first hook.

### Claim 6 (depends on 5)

The pedal of claim 5, wherein said stopper projections are formed by bending portions of said contact plate in a direction perpendicular to said contact plate.

### Claim 7 (depends on 5)

The pedal of claim 5, wherein said stopper projections are spaced apart from said first hook.
