Ribbon spring of a sprag type one-way clutch and sprag type one-way clutch

A ribbon spring of a sprag type one-way clutch, comprising an elongated strip of sheet metal including a plurality of pockets formed by punching, which is a kind of shearing, so as to be spaced apart from each other in a longitudinal direction of the strip, to define bridges between respective adjacent pairs of the pockets, the strip further including tongues each protruding from one circumferential side of one of the bridges into a corresponding one of the pockets, wherein the strip is mounted between an outer ring and an inner ring of the sprag type one-way clutch, while being bent in a circular shape such that sprags of the sprag type one-way clutch, which are inserted in the respective pockets, are biased by the respective tongues in a direction in which the sprags engage,

• wherein the tongues each have a cut surface formed by shearing at a distal end of the tongue, the cut surface including a droop, and the strip is bent in the circular shape such that the droops (58) of the respective tongues are each located on a radially outer side of the cut surface, and are in contact with the respective sprags.
