Development of novel clutch utilizing self-locking mechanisms of belt

A novel clutch was developed by using the self-locking property of belt friction. The frictional force is generated automatically by the torque applied. The belt starts to coil around the cylinder by the frictional force of the trigger pin at the end of the belt. Once the belt comes in contact with the cylinder, the belt coils automatically around the cylinder by the frictional force. Then the belt is locked firmly around the cylinder by the self-locking property of belt friction as long as driving torque is applying. The clutch is able to transmit rotational torque even in an off-centered condition.
