Initiation of coupling between an input disk (28, 128) and a clutch disk (38) at a maximum rotational coupling force without making relative rotation between the input disk (28, 128) and the clutch disk (38) is enabled only when the output shaft (12) is placed in a single engageable point within a normal reciprocal angual range of the output shaft (12). When a load applied to the output shaft (12) is equal to or greater than a predetermined value, the input disk (28, 128) and the clutch disk (38) are decoupled from one another, so that the relative rotation is made between the input disk (28, 128) and the clutch disk (38). |
