Abstract

A main clutch is interposed between an input shaft and an output shaft , and a normally engaged pilot clutch is interposed between an output member of an overrunning clutch and the output shaft . An input member of the overrunning clutch is made to freely rotate relative to the input shaft , and a cam mechanism is provided for generating a thrust force by virtue of the difference in rotational speed between the input shaft and the input member , whereby the main clutch is brought into engagement with this thrust force so generated.
