ABSTRACT:
A centrifugal type friction clutch for motor vehicles, which include: a disk serving as an output member and provided with a number of frictional coupling element support means in outer peripheral portions thereof; a drum serving as an input member and provided with a frictional coupling surface on the inner periphery thereof in coaxial relation with the circumference of the disk; and frictional coupling elements respectively supported by the frictional coupling element support means and displaceable radially outward according to the rotational speed of the disk for engagement with frictional coupling surface on the drum. The frictional coupling elements include: a friction shoe having an arcuate portion with a frictional coupling surface on the outer side thereof and abutting portions at radially inwardly projected end portions on the opposite sides of the arcuate portion; a weight having the opposite ends thereof engaged with the abutting portions of the arcuate portion; a resilient load means located between the weight and friction shoe and urging these members away from each other; and a resilient retracting means having the opposite ends thereof engaged with the frictional coupling element support means and an intermediate portion abutted against the weight; the friction shoe having one of the abutting portions engaged with one of the projections on the disk to serve as trailing shoe in driven power transmission and as a leading shoe in drive power transmission.
