Claim:
1. A centrifugal pendulum device, comprising: a pendulum mass carrier rotatable about a rotation axis; at least one pendulum mass supported on the pendulum mass carrier for movement along a track between end stops which are spaced from one another in a circumferential direction in relation to the rotation axis; and a spring device configured to urge the pendulum mass into one of the end stops, when a rotation speed of the pendulum mass carrier about the rotation axis drops below a limit rotation speed, wherein the spring device is configured to urge the pendulum mass in a radial inward direction to a first radial position, when the rotation speed drops below the limit rotation speed, said spring device having a spring element provided with a contact area and configured such that the contact area is urged toward a radial holding position, when the rotation speed drops below the limit rotation speed, so that the pendulum mass is subjected to a spring force pointing in the direction of the first radial position, and assumes a radial release position, when the rotation speed is greater than or equal to the limit rotation speed, under the influence of a centrifugal force, wherein the contact area comprises a locking element and the pendulum mass comprises at least one mating locking element, said locking element and said at least one mating locking element interacting with one another by a form fit in the circumferential direction at least when the contact area assumes the radial holding position for fixation of the pendulum mass relative to the pendulum mass carrier.
