Coupling unit for pedal assembly, and pedal

A coupling unit for a pedal assembly equipped with a human-powered vehicle, the coupling unit releasably coupling a cleat of a shoe to the pedal assembly, the coupling unit comprising:

• a first coupling member configured to releasably couple the cleat to the coupling unit, the first coupling member being configured to be disposed to a pedal body of the pedal assembly, the first coupling member having a first hole and a second hole, the first coupling member including an outer portion and an inner portion, both the inner portion and the outer portion curving toward each other, and a curvature of the inner portion being different from a curvature of the outer portion;
• a second coupling member configured to releasably couple the cleat to the coupling unit, the second coupling member being pivotable between a cleat holding position and a cleat non-holding position, the second coupling member being coupled to the first coupling member, the second coupling member having a third hole and a fourth hole;
• a shaft having a center axis, the shaft being disposed in the first hole, the second hole, the third hole and the fourth hole such that the second coupling member is pivotable about the center axis,
• the shaft having a first axial end and a second axial end opposite to the first axial end, both of the first axial end and the second axial end being non rotatably crimp-fastened to one of the first coupling member and the second coupling member;
• and
• a biasing member disposed between the first and second coupling members and including a first portion contacting the first coupling member so that the biasing member is operational in a removed state while the coupling unit is removed from the pedal assembly.
