摘要：A drivable load-carrying roller assembly comprises a conveyor roller, roller-driving structure at an end of the roller and a clutch disposed at that end for couplingthe roller to the driving structure and operable by linear displacement of structureformed on or displaceable with a guard member shielding the said driving structure. Theguard member advantageously comprises a plate displaceable in a direction at rightangles to the roller and provided with cam structure engageable with one part of theclutch for shifting that part, in the axial direction of the roller, in relation to anotherclutch part, whereby the coupling of the roller to the driving structure by the clutch iscontrolled. The said one clutch part may be spring-loaded towards its clutch-engagingposition and movable to its clutch-disengaging position by the cam structure or movabletowards both its engaging position and its disengaging position by the cam structure.
