In a preferred form, the angled release clutch system includes an inverse Belleville spring compressed between a clutch cover and a plurality of levers for biasing the levers against the pressure plate for engagement of a friction disc secured to an input shaft. The spring includes an inner annular edge portion engageable with the levers, in an outer annular edge portion engageable with the cover, which is inverse to the normal Belleville spring clutch arrangement. The pressure plate in the preferred form includes an annular inclined surface portion for the cooperating with the levers, each lever having a pressure plate contacting portion for engaging the inclined surface portion of the pressure plate.
