and, the second segment of the spring retention portion includes a second edge parallel to the line and at the first distance from the line. ### Claim 7 (depends on 1) The one-way clutch of claim 1, wherein: the first segment includes a first edge parallel to the second direction and directly extending from the neck portion; and, the second segment includes a second edge parallel to the third direction and directly extending from the neck portion. ### Claim 8 (depends on 1) The one-way clutch of claim 1, wherein the strut includes: a planar top surface facing in a fourth direction and spanning the body and the retention segment; a planar bottom surface facing in a fifth direction, opposite the fourth direction, and spanning the body and the retention segment; and, a circumferential surface connecting the planar top and bottom surfaces. ### Claim 9 (depends on 8) The one-way clutch of claim 8, wherein: the planar top and bottom surfaces include respective center points connected by an axis; and, the planar top and bottom surfaces are symmetrical with respect to a plane co-linear with the axis and passing through the spring retention portion. ### Claim 10 (depends on 1) The one-way clutch of claim 1, further comprising a spring with first and second ends, wherein: the outer race includes an indentation; the first end of the spring is disposed in the indentation; the second end of the spring is in contact with the retention segment; and, the spring urges the retention segment radially inward. ### Claim 11 (depends on 10) The one-way clutch of claim 10, wherein the second end of the spring is in contact with the spring retention segment. ### Claim 12 (depends on 10) The one-way clutch of claim 10, further comprising an inner race located radially inward of the outer race, wherein: for relative rotation of the inner and outer races in a first rotational direction, the spring urges the retention segment into contact with the inner race to non-rotatable lock the inner and outer races. ### Claim 13 (depends on 10) The one-way clutch of claim 10, further comprising an inner race located radially inward of the outer race and including a ramp surface, wherein: when the inner and outer races are not rotating, a distal surface at a distal end of the strut formed by the spring retention portion is enageable with the ramp surface such that the distal surface is parallel to the ramp surface. ### Claim 14 A stator for a torque converter, comprising: a plurality of blades; and, a one-way clutch including: an outer race: located radially inward of the plurality of blades; including a pocket; and, formed of a same single piece of material as the plurality of blades; and, a strut including: a body at least partially locatable in the pocket;
