An actuating arm drive for driving a movably mounted furniture part of a furniture item, includes at least one arrangement consisting of a compression spring and at least one guiding device for guiding the compression spring. The at least one guiding device has an at least partly variable diameter in order to compensate for a radial clearance between the compression spring and the guiding device, taking into account the change in diameter of the compression spring when the compression spring is loaded.
