However, since it is impossible to achieve such phase alignment using the configuration B in which both of the above plates are stacked alternately (3 to 4 plates each), these plates must be inserted into the clutch drum at once in a later process. I can't let you. In addition, if it is impossible to insert the plates into the clutch drum at once as described above, it is possible to alternately insert the phase-matched external and internal tooth plates one by one into the clutch drum. However, since the number of both plates is relatively large, the problem arises that the work cannot be completed within a short takt time.

The present invention is a multi-disc clutch plate phasing device that automatically aligns the phases of a large number of plates in a state in which they are stacked alternately, and inserts the plates with the same phase into a clutch drum at once. The purpose is to provide the following.
