The present invention is directed to a strut-type synchronizer mechanism having a spring member adapted for retracting and centering the blocker ring. The spring member is a leaf spring disposed within guide slots formed in the clutch hub and which is compressed between the blocker ring and the strut. The leaf spring includes a cambered surface for radially outwardly biasing the strut into contact with the clutch sleeve. In addition, the leaf spring has canted tab ends which rest upon a radial projection formed on the blocker ring for producing an axial retractive force on the blocker ring for driving the blocker ring toward a "neutral" position. The axial retractive force serves to overcome any residual viscous drag in the synchronizer mechanism created by residual friction remaining between the mating cone surfaces of the blocker ring and a ratio gear. The leaf spring further acts to retain the blocker ring in the neutral position against any viscous forces which may initiate self-energization of the synchronizer.
