ABSTRACT:
A clutch device for working vehicles including a pressure member integrally rotatable with a crankshaft of an internal combustion engine of the vehicle, a centrifugal weight supported by the pressure member, the centrifugal weight being centrifugally movable in a higher revolution region than a predetermined number of revolutions of the crankshaft, a clutch outer member driven to be rotated by the pressure member, a plurality of drive friction plates integrally supported by the clutch outer member, the drive friction plates being axially movable, a clutch inner member fixedly provided with a plurality of driven friction plates frictionally engageable with the drive friction plates and having an output portion connected to a working implement of the vehicle, and a member for resiliently biassing the drive friction plates and the driven friction plates in their engagement direction. The clutch device, in which the clutch outer member is arranged to be axially movable, further comprises a restriction member for restricting the axial movement of the clutch outer member, and a control mechanism for controlling to shift the restriction member such that the clutch outer member has an axial position thereof let to be an arbitrary element of a set consisting of, with respect to the drive and driven friction plates, a normal-open position, a frictional-engagement permitting position under effect of the centrifugal movement of the centrifugal weights, and a normal-close position.
