PROBLEM TO BE SOLVED: To provide a vibration control mechanism of a suspension capable of increasing riding comfort by suppressing the vibration of an unsprung mass. SOLUTION: An electric motor 5 is installed on a first torsion bar 36 functioning as a chassis spring through a joint bar 38 and a second torsion bar 41. The electric motor 5 is connected to the second torsion bar 41 on a side where one end of a cylinder 50 holding a rotor 51 is positioned apart from the joint bar 38. Further, a case 53 holding a stator 52 is connected to the joint bar 38 together with the other end of the second torsion bar 41. Then, a control ECU 6 controls a current providing to the electric motor 5 to attenuate the rotational speed of the rotor 51 according to the rotational speed of the rotor 51.
