Abstract
An electromagnetic clutch has a driving member and a driven member with rollers positioned between opposing non-parallel surfaces on the members. An armature operated by an electromagnet has fingers for moving the rollers into frictional engagement with the surfaces when the electromagnet is energized to engage the clutch and for moving the rollers out of engagement with at least one opposing surface when the electromagnet is deenergized to disengage the clutch.
