Abstract
Initiation of coupling between an input disk and a clutch disk at a maximum rotational coupling force without making relative rotation between the input disk and the clutch disk is enabled only when the output shaft is placed in a single engageable point within a normal reciprocal angular range of the output shaft. When a load applied to the output shaft is equal to or greater than a predetermined value, the input disk and the clutch disk are decoupled from one another, so that the relative rotation is made between the input disk and the clutch disk.
