Abstract

The invention relates to a torsional damping device which has two axially arranged parts (A and B) which are rotatable relative to one another against helical springs (18). According to the invention, at least one of the springs (18) has a variable pitch. The area of application is in particular in friction clutches for motor vehicles.
