Abstract
A clutch housing for use in a transmission is generally cylindrical or cup-shaped and has an open end. Axially-extending inner planar portions and outer planar portions are alternately disposed about the periphery of the clutch housing. Angular planar portions are disposed between the inner and outer planar portions and are continuous with the inner and outer planar portions. A retaining member is formed on each inner planar portion by lancing each inner planar portion and inwardly displacing a portion of the inner planar portion adjacent the lance. Preferably, the lance is arcuate in shape, with the arc centered toward the open end of the clutch housing. The displaced portion is formed into a retaining member, which has for its shape two generally planar, generally triangular sidewalls and a generally regular-trapezoidal wall. The trapezoidal wall has a long parallel edge and a short parallel edge. The long parallel edge is defined by the open end of the clutch housing and the short parallel edge is defined by the lance. The displaced portion of material adjacent the lance defines the abutment surface for contacting a snap ring. Preferably the trapezoidal wall has a flattened port…
