Abstract

A one-way clutch includes a pawl assembly that has one or both of directional biasing and a forward-projecting pin to ensure that the pawl engages completely with the corresponding detent. The distance between the pin tip and the free end is less than the inter-detent spacing. Before the peg swivels to a position where it might improperly engage with a detent, the non-rigid pin has already engaged with a preceding detent, and swivels the pawl further into engagement, thereby preventing the jam. A small outward biasing spring may assist.
