Abstract

A flywheel mass assembly, in particular for motor vehicle clutches, employs a flywheel mass (1) which can be driven so as to rotate round an axis of rotation (54). Fastening means (5) in the form of screws with heads (75) and shanks (74) are used to secure the assembly to a crankshaft (3). A loss preventer (12) serves to retain the fastening means (5) and prevent the fastening means from becoming detached. The loss preventer (12) takes the form of a holding ring (14) with apertures around which are disposed arrays of cantilevered gripping tongues (60). The heads (75) of the fastening means are held by the arrays of tongues (60) which are resiliently biased against the heads (75).
