VEHICULAR ACTIVE SUSPENSION DEVICE

PROBLEM TO BE SOLVED: To prevent a driving arm from being oscillated without any restriction when a connection between the driving arm of an electric actuator of an active suspension device and a suspension arm is disconnected. SOLUTION: Since a driving arm 21 arranged at an output shaft of an electric actuator A is connected to a lower arm 12 of a suspension device S through a link 22, it is possible to perform a positive moving-up or moving-down operation of the lower arm 12 with the electric actuator A and to improve a riding comfortability characteristic or a stable steering performance. Even if the link 22 is broken and a connection between the driving arm 21 and the lower arm 12 is disconnected, it is possible to prevent either the driving arm 21 or the link 22 from exceeding the predetermined range of angle, oscillating and interfering with the lower arm 12 or other members since the two stopper arms 67, 68 restrict an oscillating angle of the driving arm 21 within a predetermined range of angle.
