DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a latch disk in which the clutch hub is divided into a first clutch hub and a second clutch hub.

In a conventional clutch disc having a first clutch hub and a second clutch hub, a 6-piece clutch disc having a structure in which separate members are interposed to provide an appropriate clearance between the two clutch hubs is used.・For this reason, after long-term use, the sliding part between both clutch hubs will wear out and rust will develop. In addition, when the hysteresis was reduced and the sliding contact surface was made smaller, the contact pressure at the contact area increased and wear became more severe. .

An object of the present invention is to provide a first clutch hub and a second clutch hub.
