elements 134 are constrained the forward or left hand portion of the inner race member 130 is integrally formed with a radial flange 136 terminating in an oblique annular actuation surface 138 adapted to contact the ends of the clutch actuation fingers the right hand end of the outer race member as viewed in fig6 is formed with a radially projecting annular flange 140 defining an annular face 142 which is disposed in axially opposed relationship with respect to an annular shoulder 144 defining therebetween a cylindrical actuation groove 146 adapted to receive an actuation fork lever in a manner as previously described the outer race member is formed with a throughbore 148 which is disposed in radial clearance relationship with respect to the periphery of a supporting shaft 160 a pair of axially spaced circumferential grooves 162 are formed along the inner bore 148 of the outer race member in which a pair of resilient elements such as trilobate springs 164 are positioned and engage the periphery of the supporting shaft to maintain the bearing assembly 128 centered relative to the supporting shaft when the clutch mechanism is not being actuated the clutch bearing assembly 128 as illustrated in fig6 provides certain advantages in some instances over the arrangement.
