- and,
- in contact with the rocker.
A one-way clutch, comprising:
- an outer race including:
- a first outer race plate including:
- a first annular planar surface facing in a first axial direction parallel to an axis of rotation of the one-way clutch;
- and,
- a first pocket wall off-set, in a second axial direction opposite the first axial direction, from the first planar annular surface, and defining a first rocker pocket in the second axial direction;
- and,
- a second outer race plate including:
- a second annular planar surface facing in the second axial direction;
- and,
- a second pocket wall off-set, in the first axial direction, from the second planar annular surface, and defining a second rocker pocket in the first axial direction;
- an inner race axially disposed between the first outer race plate and the second outer race plate;
- and,
- a rocker assembly including:
