An improve spring rate of a stabilizer is provided with an extended spring length. An inner rotary part (4) of an oscillating motor (2) and a second stabilizer part (1) are connected to one another with a non-positive connection (force transmitting friction connection) designed such that the axial center of the force-transmitting length of the second stabilizer part (1) and the axial center of the force-transmitting length of the inner rotary part (4) are located on a common radial plane. The non-positive connection between the inner rotary part (4) and a fitting cylinder (14) of the second stabilizer part (1) is formed either from a shrunk-on fit or a toothed part (21) and a fitting part (22), wherein the toothed part (21) and the fitting part (22) are likewise shrunk on.
