Patent ID: 7309074

Claim:
A stabilizer control device having a first stabilizer bar and a second stabilizer bar provided between a right wheel and a left wheel of a vehicle and an actuator for applying a torsion force to the first stabilizer bar and the second stabilizer bar, comprising: the actuator comprising a motor and a speed reducing mechanism, the speed reducing mechanism comprising a first gear including a bearing portion to which the first stabilizer bar is connected and a second gear to which the second stabilizer bar is connected to generate rotation relative to the first gear, a spline shaft portion having a first external spline formed on the first stabilizer bar on one end portion thereof so as to extend in an axial direction; an internal spline formed on an inner peripheral surface of the bearing portion of the first gear so as to extend in an axial direction; a groove portion formed on a part of the spline shaft portion so as to extend in an axial direction; a toothed elastic member provided in the groove portion and having a second external spline so as to fit to the internal spline of the bearing portion; and the speed reducing mechanism comprising: a first internal gear of the first gear and a second internal gear of the second gear, in which the number of the teeth of the first internal gear differs from the number of the teeth of the second internal gear; and a paradoxical planetary gear mechanism in which a planetary gear meshes with both the first internal gear and the second internal gear.
