ABSTRACT:
An improved drive clutch device for a V-belt type automatic transmission wherein a stationary sheave is fixed to a driving shaft while a movable sheave opposed to said stationary sheave is slidably mounted on the driving shaft. A swingable cam weight and a roller in engagement with the cam weight are correlatively supported by driving shaft and movable sheave respectively. The movable sheave is caused to slide toward the stationary sheave by centrifugal force caused by rotation of the cam weight, whereby the pulley diameter is varied. The movable sheave is cylindrical in shape and has at one end an opening which is covered by a cover cast integrally with a starter pulley.
