Abstract

A centrifugal friction clutch for an automatic transmission includes axially movable friction elements supported on and rotated with an input member. Axially slidable clutch elements are supported on a clutch cover, wherein centrifugal weights held by spring members are disposed at predetermined positions on the clutch cover. First retaining means on the clutch cover press the friction members and clutch members against each other so that power can be transmitted when the centrifugal weights are displaced. A first spring bearing member contacting one end of each of the spring members urges the centrifugal weights toward their initial positions while a second spring bearing member contacting the other end of each of the spring members is held in place on the clutch cover by second retaining means engaging the clutch cover. The first and second bearing members are axially movable relative to the input member.
